Gelcoat is a highly durable coating and is the outermost structural layer on a fiberglass part, designed to protect the underlying fiberglass layers. Gelcoat is a compound that produces a high-quality finish. When cured, gelcoat combines with fiberglass to produce a smooth and durable surface that retards structural weakening from things such as water intrusion and ultraviolet light.
