Abstract
It is now feasible to coat metal objects having a substantially unexpanded surface area with a fused plasticized polyvinyl chloride coating uniformly covering and firmly anchored to the metal object. This objective is achieved by providing a metal substrate to be coated with small anchoring apertures which allow the fused coating to firmly anchor and bond onto and around the metal object and a series of leveling apertures which permit for a more uniform drainage of excessive unfused coating material from the metal object before the fusing of the coating thereto.
