Best Rubbing Compound For Heavy Oxidation: 10 Options Compared

Best Rubbing Compound For Heavy Oxidation

A strong choice for heavy oxidation cuts through degraded paint or gelcoat while matching the surface and correction job; drivers with severe automotive defects should start with Chemical Guys Insynchro Supreme Extreme Ultra Heavy Cut Paint Compound. This roundup compares ten formulas, from compounds explicitly made for heavy oxidation and sanding marks to milder products aimed at general paint correction. Surface compatibility matters: several picks target automotive paint, while Meguiar’s M49 is specifically for gel coat and fiberglass on boats and RVs.

Cut levels also differ, with listed capabilities ranging from removing 1000-grit scratches to 1500-grit scratches and finer. Check product-use restrictions before choosing, especially for 3M Super Duty Rubbing Compound, which is labeled for trained industrial and occupational customers.

The rankings prioritize oxidation fit, then the stated correction capabilities and intended surfaces.

Chemical Guys Insynchro Supreme Extreme Ultra Heavy Cut Paint Compound leads as the Best Rubbing Compound For Heavy Oxidation because its listed purpose explicitly includes removing heavy oxidation, deep scratches, and heavy sanding marks. It is described as Chemical Guys’ most powerful cutting compound for extreme paint correction, making it the clearest match for severely damaged automotive finishes. For a marine gelcoat or fiberglass surface, choose Meguiar’s M49 Heavy Duty Oxidation Remover instead; its stated compatibility is specifically gel coat and fiberglass.

Detailed Reviews: Best Rubbing Compound For Heavy Oxidation

Chemical Guys Insynchro Supreme Extreme

#1 · Best Overall

1. Chemical Guys Insynchro Supreme Extreme

  • Weight: 0.51 kg
  • Compatible Material: Metal
  • Grit Material: Aluminum Oxide

Best for: Extreme Oxidation Restoration.

Why it ranks #1: Explicitly targets heavy oxidation, deep scratches, and heavy sanding marks; the listing describes it as Chemical Guys’ most powerful compound for extreme correction.

Heavy oxidation removal alongside deep-scratch and sanding-mark correction defines Chemical Guys Insynchro Supreme Extreme. Its ultra-heavy-duty formula is aimed at severely damaged finishes, and the stated fast-cutting micro-abrasives are intended to correct challenging paint while finishing clear enough for subsequent polishing.

The combination of heavy oxidation correction and removal of deep scratches or sanding marks makes this a candidate for neglected finishes needing substantial leveling. Chemical Guys describes its precision micro-abrasives as cutting fast while finishing clear, which supports a correction-then-polish workflow rather than treating the compound as a final protection step. Aluminum oxide is the listed abrasive material, and the supplied product information gives metal as its compatible material; buyers should keep that stated compatibility in view.

Pros
  • Targets severe oxidation and deep scratches
  • Addresses heavy sanding marks
  • Precision micro-abrasives are described as fast-cutting
  • Aims to finish clear for polishing
Cons
  • The listed compatible material is metal, limiting its stated surface scope.

Skip it if you need a compound explicitly specified for clear-coat paint; Meguiar’s M105 Ultra Cut Compound lists clear coat compatibility.

This suits correction projects involving severe oxidation, deep scratches, and sanding marks where an ultra-heavy cut is the priority. Its listed compatibility is metal, so check that surface scope against the finish you intend to correct.

Meguiar's M105 Ultra Cut

#2 · Fine-Scratch Cutting

2. Meguiar's M105 Ultra Cut

  • Weight: 9.6 oz
  • Compatible Material: Plastic, Clear Coat
  • Grit Material: Micro-abrasive
  • dimensions: 1.63 x 8.25 x 3.6 in

Best for: Severe Paint Defect Correction.

Why it ranks #2: Removes moderate to heavy defects, oxidation, and sanding marks up to 1200 grit or finer, with micro-abrasives intended to limit further swirling.

Removal of sanding marks as coarse as 1200 grit gives Meguiar’s M105 Ultra Cut Compound a clear role in serious paint correction. Its ultra-fast cut also addresses moderate-to-heavy defects, including oxidation, scratches, swirls, and acid rain, while micro-abrasives are intended to limit added swirling and support gloss.

The 1200-grit sanding-mark capability makes M105 relevant after substantial paint correction, not just routine cleanup of light haze. Its micro-abrasives are specified to minimize further swirling and boost gloss, helping balance aggressive removal with a clearer finish. The listed compatible materials include plastic and clear coat, so it can suit varied automotive surfaces; the 8-ounce size is a compact quantity for focused correction work rather than a large-volume shop supply.

Pros
  • Targets moderate-to-heavy paint defects and oxidation
  • Removes sanding marks up to 1200 grit or finer
  • Micro-abrasives aim to minimize further swirling
  • Specified for plastic and clear coat
Cons
  • The 8-ounce quantity is limited for repeated large-area correction.

Skip it if you need a large-volume compound for extended shop work; Malco Super-Duty Heavy Cut Compound comes in a 32-ounce size.

Choose M105 for focused correction of oxidized paint, severe swirls, or sanding marks where a fast cut matters. The 8-ounce container suits targeted work; buyers treating large areas repeatedly should consider a larger-volume compound.

Malco Tru Grit

#3 · Fresh-Paint Use

3. Malco Tru Grit

  • Weight: 2 lb
  • Compatible Material: Painted Materials
  • Grit Material: Zirconia Alumina

Best for: Fresh-Paint And Heavy Oxidation.

Why it ranks #3: Targets heavy oxidation and environmental paint damage, removes 1000-grit-and-finer scratches, and is listed for fresh and fully cured paint.

Compatibility with paint only 24 hours old sets Malco Tru Grit apart for correction work that may begin shortly after a panel is painted. It also targets heavy oxidation, environmental damage, and 1000-grit-and-finer sanding scratches across fresh or fully cured finishes.

Its stated use on both fresh and fully cured paint gives body-shop users a correction option for panels straight out of the booth as well as established finishes. The 1000-grit-and-finer claim addresses substantial sanding marks, while correction of heavy oxidation and environmental paint damage broadens its use beyond fresh-paint work. Compatibility includes high-solids and standard clear coats, helping users match the compound to common clear-coat types listed in the product details.

Pros
  • Usable on paint 24 hours old or fully cured
  • Targets 1000-grit and finer sanding scratches
  • Addresses heavy oxidation and environmental paint damage
  • Specified for high-solids and standard clear coats
Cons
  • Its listed compatible material is painted surfaces, not gelcoat.

Skip it if you need a compound expressly specified for gelcoat; Malco Super-Duty Heavy Cut Compound targets both clear-coat paint and gelcoat.

Tru Grit suits paint-correction work spanning fresh panels, cured finishes, sanding scratches, and heavy oxidation. Its stated scope is painted materials, so boat owners working on gelcoat should select a compound with that surface explicitly covered.

3M Super Duty Compound

#4 · Automotive And Marine

4. 3M Super Duty Compound

  • Weight: 7.88 oz
  • Compatible Material: Wood
  • Grit Material: Aluminum Oxide
  • dimensions: 9.7 x 3.3 x 3.2 in

Best for: Industrial Paint And Gelcoat Work.

Why it ranks #4: Designed to cut oxidation on weathered paint and gelcoat and remove P1000-grade-and-finer scratches; its listing restricts use to trained occupational customers.

Its explicit industrial-and-occupational-use restriction is the key buying distinction for 3M Super Duty Rubbing Compound. For trained workplace users, it cuts oxidation on weathered paint and gelcoat and helps remove P1000-grade and finer scratches, with a long wet time supporting sustained correction work.

A high cut rate combined with long wet time is intended to remove imperfections with less effort while keeping the compound workable during a pass. The stated applications include automotive and marine paint and gelcoat, extending its relevance beyond vehicle panels to marine finishes. Its P1000-and-finer scratch-removal claim gives trained users a defined correction target. This is not a consumer-use choice: the supplied product information restricts it to industrial or occupational customers.

Pros
  • High cut rate targets weathered finishes
  • Helps remove P1000-grade and finer scratches
  • Addresses oxidation on paint and gelcoat
  • Long wet time supports sustained working
Cons
  • Labeled for trained industrial or occupational use, not consumer use.

Skip it if you are a consumer seeking a home-use compound; Meguiar’s Ultimate Compound is specified for DIY hand or DA-polisher application.

This is for trained industrial or occupational users correcting oxidation and fine sanding scratches on automotive or marine paint and gelcoat. Its stated workplace-use restriction is decisive, so it is not the right choice for ordinary consumer detailing.

Malco Super-Duty Compound

#5 · Larger 32-Ounce Size

5. Malco Super-Duty Compound

  • Weight: 2 lb
  • Compatible Material: Automotive, Industrial, Marine
  • Grit Material: Wool

Best for: Large-Volume Paint And Gelcoat Cut.

Why it ranks #5: A heavy-cut formula for oxidation and sand scratches on clear coat and gelcoat, with listed capability for P1500-grit-and-finer scratches.

Removal of P1500-grit and finer sanding scratches makes Malco Super-Duty a defined heavy-cut choice for automotive, marine, and industrial coatings. It also targets heavy oxidation on clear-coat paint and gelcoat, and its fast-compounding claim pairs correction with a high-gloss finish.

The P1500-and-finer capability gives buyers a specific sanding-mark target, while oxidation removal extends the compound’s use to weathered finishes. Its stated compatibility with clear-coat paint and gelcoat supports work across cars, trucks, and boats, and the high-gloss finish claim may reduce the amount of finishing work needed after cutting. A 32-ounce container makes sense for larger correction tasks or users maintaining multiple vehicles and coated surfaces.

Pros
  • Removes P1500-grit and finer sanding scratches
  • Targets heavy oxidation on clear coat and gelcoat
  • Specified for automotive, marine, and industrial coatings
  • 32-ounce quantity supports larger correction jobs
Cons
  • Its listed sanding-mark capability stops at P1500 grit and finer.

Skip it if your work requires a compound specified for 1000-grit sanding scratches; Malco Tru Grit states that capability.

Malco Super-Duty fits larger correction projects on clear-coat paint or gelcoat, especially where oxidation and P1500-or-finer scratches are involved. Its stated sanding threshold is the boundary to consider when selecting it for rougher sanding marks.

Meguiar's M49 Oxidation Remover

#6

6. Meguiar's M49 Oxidation Remover

  • Weight: 454 g
  • Compatible Material: Gel-coat and Fiberglass Surfaces
  • Grit Material: Aluminum Oxide
  • dimensions: 3.74 x 1.38 x 8.66 in

Best for: Boat And RV Gelcoat Restoration.

Why it ranks #6: Specifically made for boat and RV gel coat and fiberglass, where it removes heavy oxidation, hard water spots, and scratches.

Purpose-built use on gelcoat and fiberglass makes Meguiar’s M49 a focused option for oxidized boat and RV finishes. Its diminishing abrasives target surface defects, while feeder oils are intended to restore vibrance and shine as the compound works through oxidation.

The gelcoat-and-fiberglass compatibility makes M49 a better-matched choice for marine and RV surfaces than a paint-only compound. Its diminishing polishing-compound abrasives are specified to remove defects, while feeder oils help leave a like-new vibrance and showroom shine. The product information lists moderate and heavy oxidation, water spots, hard-water spots, scratches, and sanding scratches among its targets, giving users a broad set of surface problems to address.

Pros
  • Specified for gelcoat and fiberglass surfaces
  • Targets moderate and heavy oxidation
  • Addresses water spots, scratches, and sanding scratches
  • Feeder oils support a vibrant finish
Cons
  • Its listed compatible surfaces are gelcoat and fiberglass, not general automotive paint.

Skip it if you need a compound for clear-coat vehicle paint; Meguiar’s Ultimate Compound is specified for clear coats and gloss paints.

M49 is for boat, RV, and similar gelcoat or fiberglass surfaces affected by oxidation, spots, or scratches. Its specialized surface compatibility is the key boundary; choose a paint-focused compound for ordinary clear-coat vehicle panels.

Meguiar's Ultimate Compound

#7

7. Meguiar's Ultimate Compound

  • Weight: 1 g
  • Compatible Material: Paint
  • Grit Material: Aluminum Oxide or Silicon Carbide
  • dimensions: 8.32 x 1.03 x 0.85 in

Best for: DIY Clear-Coat Oxidation Fix.

Why it ranks #7: Removes oxidation, scratches, swirls, and water spots on gloss paint and clear coats; the listing emphasizes DIY use but does not specify a heavy-cut level.

Clear-coat-safe correction is the defining advantage of Meguiar’s Ultimate Compound: it targets oxidation, scratches, swirls, and water spots without hazing clear coats or gloss paint. The formula is presented as a way to restore color and clarity, with application by hand or dual-action polisher for a practical home paint-care workflow.

Its stated coverage of oxidation, swirls, scratches, and water spots makes it useful when faded paint has several visible imperfections rather than oxidation alone. Clear-coat safety and compatibility with all gloss paints help buyers choose it for common painted finishes, while hand or DA-polisher application accommodates either manual work or machine correction. Meguiar’s also says it cuts quickly and leaves a good-looking finish, reducing the effort involved in refreshing neglected paint.

Pros
  • Targets oxidation, scratches, swirls, and water spots
  • Specified as safe for clear coats and gloss paints
  • Can be applied by hand or DA polisher
  • Aims to restore paint color and clarity
Cons
  • Listed compatibility is paint, rather than gelcoat or fiberglass.

Skip it if you need a compound expressly specified for gelcoat or fiberglass; Meguiar’s M49 Heavy Duty Oxidation Remover is the marine-focused option.

For DIY owners correcting oxidation and several paint defects on clear-coat or gloss-painted vehicles, this offers hand or DA flexibility. Its stated surface fit is paint, so marine gelcoat and fiberglass call for a more specialized choice.

ABRO Rubbing Compound

#8

8. ABRO Rubbing Compound

  • Weight: 300 g
  • Compatible Material: Metal, Glass, Plastic, Composite
  • Grit Material: Clay

Best for: Weathered Paint Quick Correction.

Why it ranks #8: Made for dull, faded, weathered, or oxidized paint and targets scuffs and light scratches, but the listing gives no grit-removal capability.

Fast-cut correction for dull, faded, weathered, or oxidized paint is the central use of ABRO Rubbing Compound. It also targets paint transfer, scuffs, stains, swirl marks, and minor scratches, giving owners a single compound aimed at the surface blemishes that accumulate through everyday driving.

The formula’s oxidation focus makes it relevant when paint looks dull or weathered and a basic polish is not the intended level of correction. Its additional targets—paint transfer, scuffs, swirls, stains, and minor scratches—let buyers address several common surface issues in one correction session. The listed compatible materials include metal, glass, plastic, and composite, offering broader stated material coverage than paint alone; the 10-ounce container is a manageable quantity for personal detailing.

Pros
  • Fast-cut formula targets oxidized and faded paint
  • Addresses paint transfer, scuffs, and swirl marks
  • Also targets stains and minor scratches
  • Lists compatibility with metal, glass, plastic, and composite
Cons
  • Its scratch claim is limited to minor scratches, not deep defects.

Skip it if you need removal of deep scratches and heavy sanding marks; Chemical Guys Insynchro Supreme Extreme targets those severe defects.

ABRO fits owners refreshing weathered paint and reducing daily-use blemishes such as scuffs, transfer, and minor scratches. Its stated scratch scope is minor, so severe sanding marks or deep damage call for a more aggressive correction product.

Turtle Wax T230A Rubbing Compound

#9

9. Turtle Wax T230A Rubbing Compound

  • Weight: 10.5 oz
  • Compatible Material: Metal
  • dimensions: 27 x 4.5 x 2 in

Best for: Heavy-Duty Everyday Paint Cleaning.

Why it ranks #9: Its heavy-duty formula lists oxidation and deep-scratch removal on automotive paint, though it provides no specific sanding-grit capability.

Heavy-duty cleaning power that targets both oxidation and road grime gives Turtle Wax T230A a broad maintenance role. Its formula is also specified for deep scratches and swirl marks across automotive paint finishes, making it relevant when visible paint defects arrive alongside dirt and contaminants.

The combination of oxidation correction with removal of road grime and tough stains makes this useful for paint that needs more than a light polishing pass. Its stated coverage of deep scratches and swirl marks broadens the job to include visible defects, while compatibility with automotive paint finishes supports vehicle-panel use. The 10.5-ounce container keeps the product in a practical size for owner detailing; the supplied information does not specify a sanding-grit removal threshold.

Pros
  • Targets oxidation across automotive paint finishes
  • Cuts through road grime and tough stains
  • Addresses deep scratches and swirl marks
  • 10.5-ounce size suits owner detailing
Cons
  • No specific sanding-grit removal capability is stated in the supplied details.

Skip it if you require a defined sanding-mark threshold; Malco Tru Grit specifies removal of 1000-grit and finer sanding scratches.

T230A suits vehicle owners tackling oxidation, grime, stains, scratches, and swirls in a general paint-cleaning session. If your correction plan depends on a stated sanding-grit threshold, choose a product whose listed capability defines that target.

3D One Compound Polish

#10

10. 3D One Compound Polish

  • Weight: 8 oz
  • Compatible Material: Ceramic
  • Grit Material: Ceramic

Best for: One-Step Cut And Polish.

Why it ranks #10: Combines cutting and polishing to address oxidation and scratches, but it is positioned as a one-step correction product rather than a heavy-oxidation specialist.

A hybrid cutting-compound and finishing-polish formula is 3D One’s defining convenience: it combines correction and finishing in one step. The product targets oxidation, scratches, and swirls on tired or faded paint, while its zero-dust claim supports a tidier polishing session across paint colors.

Combining cutting and finishing functions can streamline a correction session by reducing the need to switch between a separate compound and polish. Its stated targets include oxidation, scratches, and swirls, making it relevant when faded paint has multiple visible defects. The zero-dust formula is presented as producing a clean finish on any paint color, while the product’s 8-ounce size is suited to smaller correction jobs or keeping a compact detailing supply.

Pros
  • Combines cutting compound and finishing polish
  • Targets oxidation, scratches, and swirls
  • Zero-dust formula is claimed for any paint color
  • Aims to restore clarity and gloss
Cons
  • The 8-ounce size provides less compound for broad-area correction.

Skip it if you need a larger quantity for extensive correction; Malco Super-Duty Heavy Cut Compound is supplied in a 32-ounce size.

3D One fits enthusiasts seeking a simplified correction-and-finish step for faded paint with oxidation, scratches, or swirls. Its 8-ounce size is a consideration for broad panels or repeated jobs, where a larger container may suit better.

Avoid matching a gelcoat formula to paint by assumption

A compound labeled for gelcoat or fiberglass is not automatically the right choice for automotive paint. Meguiar’s M49 Oxidation Remover is specifically described for boat and RV gel coat and fiberglass, while the Chemical Guys Insynchro Supreme Extreme is described for extreme paint correction and lists metal compatibility. Malco Tru Grit is listed for painted materials and both fresh and fully cured paint.

These distinctions matter when oxidation appears on a boat, RV, or car: choose by the actual surface, not just the word oxidation on the label. 3M Super Duty Compound also addresses gelcoat and automotive paint, but its listing says it is for trained industrial and occupational customers and not for consumer use.

That usage restriction can rule it out for a typical DIY buyer regardless of its heavy-cut claims.

Heavy correction can leave a finish needing another step

A heavy-cut compound may correct oxidation without being the last product needed for the finish. The listings show a useful trade-off: Chemical Guys Insynchro Supreme Extreme emphasizes extreme cutting, while 3D One Compound Polish is designed to combine cutting and finishing in one step. Meguiar’s M105 Ultra Cut describes fast defect removal and micro-abrasives that minimize further swirling, but that does not establish that every finish will be ready for protection immediately afterward.

Meguiar’s Ultimate Compound likewise highlights a clear finish without hazing on clear coats and gloss paints. Treat these as different product aims, not a guarantee that a single compound will deliver the same final appearance on every damaged surface.

If the oxidation is severe, prioritize a formula that explicitly lists heavy oxidation; if reducing steps matters more, consider the hybrid option while recognizing its listing does not specify a heavy-cut grit range.

How to Choose a Compound for Heavy Oxidation

Match the surface

Look first for a formula that names the surface you need to correct. Meguiar’s M49 Oxidation Remover is specifically for gel coat and fiberglass, including boat and RV finishes. Chemical Guys Insynchro Supreme Extreme lists metal compatibility and is described for extreme paint correction; Malco Tru Grit lists painted materials and fresh or fully cured paint.

Malco Super-Duty Compound covers clear coat and gelcoat, while 3M Super Duty Compound also lists automotive and marine paint and gelcoat but restricts its intended use to trained occupational customers. Choose the specialized marine formula for gelcoat or fiberglass; for vehicle paint, favor a product whose description directly addresses paint correction and check its stated compatibility.

Check the stated cut capability

Choose a cut level that reflects how severe the oxidation is and whether sanding scratches also need correction. Meguiar’s M105 Ultra Cut lists removal of sanding marks up to 1200 grit or finer; Malco Tru Grit lists 1000-grit-and-finer scratches; Malco Super-Duty lists P1500-grit-and-finer scratches. Chemical Guys Insynchro Supreme Extreme explicitly targets heavy oxidation and heavy sanding marks, but gives no grit number in the supplied data.

The grit figures describe listed scratch-removal capabilities, not a guarantee for every surface. For severe damage with sanding marks, prioritize a heavy-cut product with a relevant stated capability; for oxidation without stated sanding marks, an explicitly oxidation-focused formula may be the closer fit.

Decide between correction and one-step use

Consider whether you want a dedicated cutting compound or a product that combines cutting with finishing. Chemical Guys Insynchro Supreme Extreme and Meguiar’s M105 Ultra Cut emphasize strong defect removal, while 3D One Compound Polish is described as both a cutting compound and finishing polish in one step. Meguiar’s Ultimate Compound is positioned for DIY use by hand or with a DA polisher and says it is safe on clear coats and gloss paints.

These descriptions represent different priorities, not interchangeable levels of cut. For neglected paint with heavy oxidation, favor the products that state heavy-cut capability; if fewer steps are more important and the damage is less severe, a hybrid or DIY-oriented formula may suit the job better.

Which Compound Should You Choose for Heavy Oxidation?

For severely oxidized automotive paint, choose Chemical Guys Insynchro Supreme Extreme: it explicitly targets heavy oxidation, deep scratches, and heavy sanding marks. If you want a stated grit capability, Meguiar’s M105 Ultra Cut removes marks up to 1200 grit or finer, while Malco Tru Grit lists 1000-grit-and-finer correction and suitability for fresh or fully cured paint. For boat or RV gelcoat and fiberglass, Meguiar’s M49 Oxidation Remover is the surface-specific pick.

Malco Super-Duty Compound lists clear coat and gelcoat use and P1500-grit-and-finer removal, but 3M Super Duty Compound is labeled for trained occupational customers, not consumers. For less severe DIY paint correction, Meguiar’s Ultimate Compound offers hand or DA use; 3D One Compound Polish combines cutting and polishing.

Frequently Asked Questions

How can I tell whether oxidation is too deep for a rubbing compound?

If oxidation remains after a small, careful test area, or the paint is peeling, cracking, or missing, a compound may not be enough. Compounds are intended to correct the surface, not replace failed paint. For severe damage, consider professional assessment before continuing, especially if you are unsure how much finish remains.

Should I use a machine or apply rubbing compound by hand?

Choose based on the product directions, surface, and your experience. Meguiar’s Ultimate Compound is described as suitable for hand or DA use, while other listed products may have different application guidance. Work a small area first, follow the label, and avoid using a machine if you are not comfortable controlling it.

What should I apply after compounding to protect the restored finish?

Apply a compatible paint protectant, such as wax or a sealant, after the corrected surface is clean and dry. Compounding corrects the finish but does not itself provide lasting protection. Follow the protectant’s directions, and check the compound label for any preparation steps before applying another product.

Which compound is suited to boat or RV gelcoat and fiberglass?

Meguiar’s M49 Heavy Duty Oxidation Remover is the surface-specific choice in this roundup because its stated compatibility includes gel coat and fiberglass. For automotive paint, the editorial pick for severe oxidation is Chemical Guys Insynchro Supreme Extreme. Check each product label to confirm it suits your particular surface.

Which listed compounds state a grit capability?

Meguiar’s M105 lists removal of marks up to 1200 grit or finer, while Malco Tru Grit lists 1000-grit-and-finer correction and suitability for fresh or fully cured paint. Malco Super-Duty Compound lists P1500-grit-and-finer removal. These claims do not make the products interchangeable; match the stated use to the surface and task.

Final Words

For severely oxidized automotive paint, choose Chemical Guys Insynchro Supreme Extreme: its stated purpose directly covers heavy oxidation, deep scratches, and heavy sanding marks. For boat or RV gelcoat and fiberglass, choose Meguiar’s M49 instead. If grit capability matters, compare the listed claims for M105, Tru Grit, and Malco Super-Duty.

For less severe DIY correction, consider Ultimate Compound for hand or DA use, or 3D One for combined cutting and polishing.
