Meguiar's M4916 Heavy Duty Oxidation Remover, 16 oz, Marine and RV Gel Coat and Fiberglass Compound
Meguiar's M4916 Heavy Duty Oxidation Remover, 16 oz, Marine and RV Gel Coat and Fiberglass Compound
Meguiar's M4916 Heavy Duty Oxidation Remover is a 16 ounce marine and RV compound formulated to clear heavy surface oxidation, water spots, stains, and scratches from gel coat and fiberglass surfaces. It uses diminishing polishing compound abrasives, a fine 1500 grit aluminum oxide formula, that break down and disappear during application, cutting through oxidation and discoloration without leaving a harsh, unfinished surface behind. As the abrasives work, feeder oils are released into the surface to restore color vibrancy, gloss, and a like-new shine to faded or chalky gel coat.
This compound is built for the specialized finishes found on boats, RVs, and jet skis, where sun and water exposure cause more aggressive oxidation than typical automotive paint. It can be applied by hand for precise, controlled work, or with a dual action polisher for faster coverage; a high-speed rotary buffer can be used for a more aggressive cut on heavier oxidation. The formula is compatible with gel coat and fiberglass surfaces. Each bottle contains 16 fluid ounces of product in a plastic container. For longer-lasting protection after compounding, follow up with a marine sealant to lock in the restored finish.
