If 3M Marine Cleaner & Wax didn't do the trick, step up to 3M Marine Restorer & Wax. This cleaner wax offers the same one-step performance but it has more cleaning power to remove heavy oxidation. Improve the color and shine of your boat while adding durable protection with 3M Marine Restorer & Wax. 3M Marine Restorer & Wax is designed for older boats with faded, oxidized paint. Perhaps the boat has always been stored outdoors or it's never been polished or waxed. 3M Marine Restorer & Wax is what you need to restore the shine and color. 3M Marine Restorer & Wax removes HEAVY oxidation, chalking, fading, minor scratches, rust and exhaust stains. At the same time, it lays down clear, glossy protection on fiberglass/gel coat.
Apply 3M Marine Cleaner & Wax with a polisher for quick, even coverage. The FLEX XC 3401 VRG Orbital Polisher or the Porter Cable 7424XP Dual Action Polisher are great choices for their ease of use and dependable performance. Use a foam polishing pad. You may need two or more extra pads on hand depending on the size of the boat or RV and the severity of oxidation. Use a soft Cobra All Purpose Microfiber Towel to buff the fiberglass to a smooth shine.
