ABSTRACT:
Two spray coatings are successively applied, without an intervening curing step, to coat the inside surface of a shell for a two-piece can. This "wet-on-wet" coating technique utilizes zone spraying, wherein only the sidewall is covered during the first application, with the second coat being applied to all inside surfaces.
