Removing heavy oxidation from fiberglass RVs, boats and cars is an important part of your RV, boat or auto maintenance plan. The dull surface appearance, oxidation, is caused by the sun's ultra-violet rays. If caught quickly it can be removed easily, but if it is left untreated for long periods of time, the gelcoat surface can permanently fade and require professional removal and repainting. To restore and retain the glossy shine that is inherent in fiberglass, it is necessary to remove the oxidation and expose a clean layer of fiberglass.
Items you will need
Moderately abrasive polish or wax that is formulated specifically to remove oxidation
Dampen a soft cloth with a moderately abrasive polish or wax that is formulated specifically to remove oxidation from fiberglass and apply the polish to the fiberglass in an overlapping circular motion, working one section at a time. Turn the cloth over (when it becomes covered with the color of the fiberglass) and dampen it with the polish as often as needed to cover the entire fiberglass surface area.
Allow the polish to dry to a dull overall finish on the surface. This will take approximately 30 minutes.
