System for making bright aluminum parts

摘要

An aluminum object is manufactured by a process including chromate conversion coating of the aluminum object; sequentially applying a urethane resin primer coat to the outer surface and thereafter applying a dielectric substrate urethane resin basecoat; vacuum metallizing a corrosion prone metal on the dielectric substrate basecoat to form "islands" which are chemically etched and then are top coated with a clear resinous layer to encapsulate and insulate the islands, one from another.
