THE APPEARANCE REQUIREMENTS FOR AUTOMOTIVE EXTERIOR PANELS ARE VERY STRINGENT AND ARE SUMMARIZED IN THE TERM CLASS A SURFACE QUALITY. A MAJOR DIFFICULTY IN THE SUCCESSFUL APPLICATION OF PLASTIC COMPOSITE MATERIALS SUCH AS SMC, RTM, ETC. TO AUTOMOTIVE EXTERIOR PANEL APPLICATIONS IS THE ACHIEVEMENT OF ACCEPTABLE CLASS A SURFACE QUALITY IN A HIGH-VOLUME PRODUCTION ENVIRONMENT. AN INSPECTION TOOL TO PROVIDE A MEANS TO RAPIDLY DETERMINE THE SURFACE QUALITY OF AUTOMOTIVE PANELS IN A FULL FIELD NONCONTACT MANNER IS DISCUSSED.
