ABSTRACT:
A liquid thermoset coating is described for application on and near surfaces of molded plastic parts where the resin rich phase has been disturbed or imperfectly formed. The coating has been found to be effective at minimizing paint pops and craters in subsequent finish coatings on said parts. Said paint pops and craters develop during heated cure cycles for the finish coatings. The coating which is applied to the heated part and subsequently cured is preferably an epoxy composition of low viscosity. The molded plastic parts are preferably fiber reinforced thermoset polyester parts with an in-mold coating to improve surface quality.
