1. A method of manufacturing a coating for a vehicular component, comprising the steps of:
providing a mold for making a vehicular component, the mold having a mold surface; coating the mold surface with an in-mold coating composition, said in-mold coating composition comprising: a non-polyol aqueous copolymerisate dispersion comprised of acrylic esters and styrene; a microspersion wax additive; a flattening agent; water; n-butanol; a thickening agent; and a flow additive; passing a polyurethane composition into the mold and into contact with the in-mold coating composition; and causing the in-mold coating composition and polyurethane composition to cure, so as to form the coating for the vehicular component.
