Marine and Boat Heavy Compound removes deep scratches and swirls from gelcoat and fiberglass with an advanced high grade abrasive technology to cut and refine gloss and shine on watercraft.

  • Advanced abrasive technology
  • Designed specifically for boats and watercraft

Versatile For All Watercrafts Parts

Boat Heavy Compound cuts away defects, scratches, and contamination from painted finishes, aluminum, fiberglass, gel coat, polished metal, and plastic parts from any watercraft. Cut away faded gel coat and oxidized paint from sun-beaten parts above the waterline to restore luster and shine. Cut back crusty barnacles and salt buildup from below the waterline for a smooth finish with improved performance through the water. Erase heavy water spots and oxidation from metal rails and trim pieces for a bright and true reflection.

Prepare Surfaces For Final Polish And Deep, Lustrous Shine

Polishing with a machine is the only way to permanently repair surface defects like swirls, scratches, and oxidation without resorting to drastic measures like repainting and refinishing a surface. Heavier levels of contamination, oxidation, and damage like swirls and scratches require heavier abrasives and compounds to cut away the deeper defects. Boat Heavy Compound knocks down the heaviest damage and defects to set up the rest of the polishing process for success.
