Meguiar's #49 Mirror Glaze HD Oxidation Remover - 1 Gallon

Meguiar's #49 Mirror Glaze HD Oxidation Remover is a professional-grade compound engineered to restore weathered fiberglass gel coat on marine vessels and RVs. After years on the water, your boat's exterior takes a beating from UV exposure, saltwater spray, and oxidation that dulls the finish and ages the hull prematurely. This 1-gallon formula tackles moderate oxidation, scratches, stains, and stubborn water spots in a single application, making it an essential maintenance product for boat owners who demand showroom clarity without professional detailing costs.

The HD formula works by chemically breaking down oxidized gel coat layers while micro-abrasives gently cut through surface degradation and restore color depth. Unlike lighter polishes, this heavy-duty compound is formulated specifically for marine fiberglass and RV surfaces, where traditional automotive products often fall short due to the unique composition of marine gel coat. The effortless application means you spend less time buffing and more time enjoying your boat—a critical advantage when working on large hull areas or preparing for extended trips. The 1-gallon size provides substantial coverage for multiple applications or larger vessels.

Serious boaters and RV enthusiasts benefit most from this product, particularly those with moderate oxidation or long-term sun exposure who want to avoid costly professional restoration. It works on all fiberglass gel coat surfaces—hulls, cabin tops, and trim—making it versatile enough for mixed-material vessels. Apply with a foam applicator pad or orbital polisher, working in sections and buffing with a microfiber cloth for best results. Compatible with standard marine waxes and sealers for a complete protective finish.
