Gelcoat refers to the material used to provide a high-quality gloss finish on the visible surface of a fiber-reinforced composite material, such as fiberglass. Most common gelcoats are based on epoxy or polyester resin chemistry. They can be colored and will retain a durable high gloss surface. Many watercraft and bathroom fixtures utilize an outer layer of gelcoat, which can become worn, chipped, or cracked. We also offer repair kits for fiberglass boats, RVs, surf boards, and laminate countertops.
