Description of use

The reinforcement,in form of fiberglass strands, mat or woven roving, is first laid into amold which has been coated with a release agent and agel coat. Then a resin mix is applied by hand using a brush or spray gun. A roller is then used to ensure uniform impregnation, complete glass wet-out and removal of any trapped air bubbles. This operation is repeated until the desired thickness of the structure is obtained. After curing at room temperature or under heating conditions,the finished parts are formed.
