Meguiar's M105 Ultra-Cut Compound 8oz — Professional rubbing compound for heavy defect removal, fast cutting and clear-coat safe

Meguiar's M105 Ultra-Cut Compound (8oz) is a professional-grade rubbing compound designed to rapidly remove heavy paint defects and sanding marks while restoring deep gloss.

Engineered for detailers and body shops but simple enough for skillful DIYers, this Mirror Glaze formula uses super micro-abrasive technology to shave through oxidation, moderate to heavy swirls, scratches and up to 1200-grit sanding marks without leaving a dull, hazy finish. It works on all glossy paints and clear coats and can be applied by hand, dual-action polishers, or high-speed rotary buffers. Follow up with a refining polish such as Meguiar’s M205 for the best mirror-like shine before sealing with your preferred wax or coating.

How quickly will M105 remove sanding marks and scratches?

M105 is formulated for fast cutting power, removing sanding marks as fine as 1200 grit and addressing moderate to heavy surface defects. It balances aggressive abrasion with micro-abrasives so you get speed without sacrificing the ability to achieve a high-gloss result.

• Removes sanding marks from 1200 grit or finer
• Lift oxidation, acid rain etching, and deeper swirls
• Works efficiently with a rotary buffer or dual-action polisher

Will using M105 harm my clear coat or paint?

When used correctly, M105 is safe on all glossy factory and custom clear coats. The formula is designed to cut defectively while minimizing additional micro-marring, but proper technique, pad choice, and speed are important to avoid overworking a panel.

• Clear-coat safe on glossy finishes
• Adjust aggressiveness by pad type and machine speed
• Follow with a finishing polish (e.g., M205) to remove light holograms

Which application method gives the best results: hand or machine?

M105 performs well both by hand and with machines. For fastest correction and consistent results, professionals typically use a dual-action polisher or rotary buffer; hand application can work for spot fixes or small panels where machine access is limited.

• Dual-action polisher: safer, consistent cut with lower risk of swirl
• Rotary buffer: maximum cutting speed for severe defects
• Hand application: precise control for edges and small areas

What should I do after using M105 for the best gloss?

Always refine the surface after heavy cutting. Use a fine finishing polish like Meguiar’s M205 to erase any remaining light swirls or holograms and boost depth. Finish by applying a protective wax, sealant, or coating suited to your needs.

• Follow M105 with M205 for refined clarity and added shine
• Apply a wax or paint protection product to lock in gloss
• Inspect under bright light to confirm defect removal

Who is this for: Meguiar's M105 Ultra-Cut Compound is made for professional detailers, collision repair shops, and experienced enthusiasts who need a powerful, reliable compound to remove heavy defects quickly. If you want to correct severe paint issues while preserving a high-gloss finish and you have the tools or skill to use a polishing machine, M105 is a strong candidate. Less experienced users should practice technique on inconspicuous panels and always pair M105 with a finishing polish and protective topcoat for best results.

Features include rapid defect removal, super micro-abrasive technology for a superior finish, clear-coat safety on glossy paints, and versatility of hand or machine application.
