Abstract

The invention relates to a dish rack (30) with a protective coating (50) comprising an electrocoated layer (54) and a polymer layer (58). The coating also includes a base corrosion-resistant layer (52) on the metallic dish rack (30) and a primer layer (56) adjacent to the electrocoated layer (54) to improve adhesion of the polymer layer (58). The aesthetically appealing exterior coating protects the dish rack (30) from corrosion and from corrosion propagation.
