When the boat is not in use, keep the gelcoat surface out of the sun or covered with a canvas tarpaulin. Do not use plastic or other non-porous materials, which can trap moisture between the cover and the surface.
-
Wash the surface with a mild detergent.
For best results, use a cleaner recommended for fiberglass and follow the instructions on the label of the product.
Do not use automatic dishwasher detergent, abrasives, bleaches, and strong chemicals with acids/bases or ammonia.
-
Wax the surface at least twice yearly to restore gloss and protect the finish.
Only use wax recommended for fiberglass and follow the instructions carefully.
Never wax a gelcoat surface in direct sunlight.
