Gel coat is a type of resin used primarily in the manufacturing of fiberglass products. It serves as a protective outer layer that provides a smooth, glossy finish, enhancing the appearance and durability of items like boats, swimming pools, and automotive parts. Gel coat is typically applied as a thick layer before the fiberglass is laid down, allowing it to cure and bond effectively. In addition to its aesthetic benefits, gel coat also offers resistance to water, UV rays, and chemicals, making it ideal for outdoor applications. Regular maintenance, such as cleaning and polishing, can help preserve its appearance and extend the lifespan of the underlying fiberglass structure.
