The Body Division of the Automotive Corrosion and Prevention Committee of SAE (ACAP) concluded that an automotive body corrosion survey for public consumption was needed. The committee proceeded to develop a survey methodology and conducted an initial survey in the Detroit area. Similar surveys can be conducted at regular biyearly intervals for comparison to track the results of industry wide improvements in corrosion protection. Over two hundred 1980 and 1981 model year vehicles were surveyed covering a wide range of domestic models and some foreign models. Twenty six panel or partial panel categories were developed and evaluated for a closed car parking lot survey. Each panel was checked for perforation, blistering and surface rust.
