The gelcoat layer is composed of a thermoplastic or thermoset resin and plasticizer. The matrix includes fillers, colorants and plasticizers dispersed therein and is laid up on the inner side of the gelcoat layer. The backup layer is comprised of a fibrous polyester sheet impregnated with thermoplastic or thermoset resin and plasticizer. The fibers used in the fibrous sheet may be woven or nonwoven, and are preferably of a polyester material. The backup layer is laid up on the matrix layer. The matrix layer and backup layer may each include microspheres.
