Abstract
A method for improving the properties of a coated reinforced thermoplastic substrate which forms surface irregularities when cooled after being heated to elevated temperatures is disclosed. The method comprises coating the substrate with primer coating compositions, wet-on-wet, comprising first applying a rigid primer composition followed by applying a flexible primer composition, curing the composite primer coating and thereafter applying a topcoating. The coated substrates exhibit improved properties, especially distinctness of image (DOI).
