Gelcoat is the durable, glossy finish on the exterior surface of fiberglass. Maintaining the gelcoat layer is the key to keeping your boat looking brand new on the water year after year. Scrapes and dings also happen and doing annual maintenance at the beginning of the boating season can help you stay on top of keeping your gelcoat in pristine condition.
Avoid spraying directly into electronics, windows, and doors. Rinse the boat completely with freshwater, removing all saltwater and ensuring cleaners won’t bake into the glass, fiberglass, or rubber. Continue to rinse as needed throughout the wash to keep soap from drying. Wash the boat from the top down, forward to aft.
