Our 3M™ Perfect-It™ Gelcoat Heavy Cutting Compound features a fast-cutting formula that removes heavy oxidation, weathering, dulling, chalking and scratches from gelcoat surfaces. Excellent for boats, watercraft and RVs, this professional-grade marine compound is formulated to stay wet for a long time on the compounding pad and on the surface, so you don’t have to stop as often to change pads or apply more material. It leaves a smooth finish ready for boat polish and wax. 3M™ Perfect-It™ Gelcoat Heavy Cutting Compound is part of a family of gelcoat finishing products. 3M™ Perfect-It™ Boat Wash, 3M™ Perfect-It™ Gelcoat Medium Cutting Compound + Wax, 3M™ Perfect-It™ Gelcoat Light Cutting Polish + Wax and 3M™ Perfect-It™ Boat Wax are all available for every type of boat and RV maintenance.
