Five passenger vehicles used around the Detroit area were submitted for corrosion investigation. They were manufactured in 1989 and 1991. Panels forming the body shell were classified into five categories according to the corrosion environment, and their cosmetic corrosion and perforation corrosion were evaluated. It was confirmed that exterior panels made of two-sided zinc coated steel sheet has excellent performance in cosmetic corrosion, and it was shown that corrosion depth at lapped parts under low humid conditions decreases with increased zinc coating weight. For precoated panels with zinc coating more than 45 g/m2, the degree of corrosion was very low.
