3D Marine & RV Cutting Compound is a heavy-duty marine cutting compound for fiberglass and gel coat when oxidation, scratches, and weather damage are past what a polish can fix.

Engineered for marine/RV gel coat abuse—salt, sun, and years of neglect—rather than a light automotive finishing polish.

Why detailers keep it on the cart

• Professional cutting power for severe gel coat oxidation and defects (product page)
• Built specifically for marine and RV restoration challenges
• Concentrated abrasives aimed at efficient cut with less wasted effort
• Creates a clean foundation before finishing polish
• Machine/pad matrix not published—test on a sample area

How to use

Use with an appropriate cutting pad on oxidized gel coat, work until the surface clears, wipe residue, then refine with Marine & RV Finishing Polish (630) as needed.
