ABSTRACT:
A bright trim article is manufactured by a process including applying a primer coat material to the outer surface of a raw part and thereafter applying a dielectric substrate basecoat by rotation and spray painting to prevent orange peel; thereafter vacuum metallizing a corrosion prone metal, namely indium, on the dielectric substrate basecoat to form "islands" of the indium that are etched following the growth of the metal as it is deposited after the nucleation stage and the stage of channelization but before the formation of an electrically conductive film; thereafter applying a clear resinous topcoat material by rotating the base-coated part and spraying the resinous topcoat material to prevent an orange peel surface while filling the channels and covering the islands to encapsulate and insulate the islands, one from another.
A preferred application of this invention is the manufacture of trim parts for the automotive, plumbing and building industries.
