Polyester Gelcoat is used to provide a high-quality visually pleasing finish on the surfaces of a fiber-reinforced composite material. The most common gelcoats are based on epoxy or unsaturated polyester resin chemistry. Gelcoats are modified resins that are applied to molds in a liquid state. Once cured, the gelcoat forms cross-linked, polymers and are then backed with a composite matrix. Often this matrix is a mixture of polyester resin, fiberglass, carbon fiber ; and in some cases epoxy resin with fiberglass.

When fully cured, the reinforced composite is removed from the mold,  and will present the finished gelcoat surface. This is usually pigmented to provide a glossy surface, which improves the aesthetic appearance of the completed composite, such as a fiberglass boat hull or carbon fiber hood.

Many wood or fiberglass boats and aircraft are manufactured using carbon fiber and fiberglass composite materials with an outer layer of gelcoat, typically 0.5 mm to 0.8 mm (0.02 in to 0.03 in) thick. Polyester gelcoat is designed to be durable, and provide protection from the ultraviolet rays of the sun and water.

Specialized gelcoat such as those used for tooling can be used to manufacture the molds, which in turn are used to manufacture composite parts. These gelcoats have a very high level of durability to overcome the mechanical and thermal stresses during the curing and de-molding processes.

In addition to any pigment a gelcoat will, if necessary, contain a thixotropic additive to assist its ability to stick to vertical portions of the mold while curing.
