Restore the Shine and Sparkle in Your Boat
3M™ Marine High Gloss Gelcoat Compound revives the sparkle and shine that makes a boat glisten out on the water on a sunny day. Compounding removes the scratch pattern left by abrasives in previous sanding applications. You can expect it to effectively remove P600 and P1000 sanding scratches in the gelcoat.
A High Quality Finish
Our high gloss gelcoat compound produces a high quality professional finish. The unique paste formulation contains no wax or silicone and reduces slinging. 3M™ Marine High Gloss Gelcoat Compound is recommended both for boats requiring more extensive restoration work and boats that need simple upkeep to maintain a shine. Its fast-cutting formulation reduces compounding time, making boat restoration a quicker and easier task. For an even higher-gloss finish, use 3M™ Marine Finesse-it™ II Glaze.
In addition to boats, 3M™ Marine High Gloss Gelcoat can also be used on other vehicles with fiberglass and painted surfaces such as RVs and personal watercraft.
Better Science for Better Boating from 3M
Our 3M™ Marine High Gloss Gelcoat Compound benefits from decades of development in cleaning and fabric protection including our trusted Scotchgard™ and Scotch-Brite™ brands. It’s a terrific example of how 3M applies science to the lives of boating enthusiasts for better, cleaner boating.
