Abstract
A method of coating a fiber-reinforced plastic substrate is disclosed. The method comprises the application of a primer coat directly to the fiber-reinforced plastic substrate. The primer is an organic resinous composition comprising a polyepoxide and a polyacid curing agent. A topcoat is then applied to the primer coat. The composite coating using the polyepoxide-polyacid primer provides for coated fiber-reinforced plastic substrates with excellent appearance as well as good chip resistance and adhesion, as well as tolerance to overbaking conditions.
