3M Perfect-It Gelcoat Heavy Cutting Compound

Heavy Cut Gelcoat Compound for Fast Oxidation Removal & Surface Restoration

A high-performance heavy cutting compound engineered to remove severe oxidation, scratches and surface defects while restoring gelcoat to a high-gloss finish.
This fast-cutting formula is designed as the first step in professional gelcoat restoration, delivering aggressive defect removal on heavily weathered and chalked surfaces. It quickly eliminates oxidation, scuff marks, water stains and sanding scratches, making it ideal for restoring faded or neglected marine and fiberglass finishes. With a long wet time, it allows extended working periods and easier clean-up while reducing product consumption. Suitable for boats, RVs and industrial gelcoat surfaces, it provides consistent cutting performance without excessive heat build-up or pad clogging. Designed for use with rotary polishers and wool compounding pads, it significantly reduces restoration time while preparing surfaces for polishing and finishing stages.
