Abstract
Abstract The method is very specifically directed to the refinish painting of automobile door panels, in particular a panel which is sub-divided along a longitudinal demarcation zone into two surface sections, in which an adhesive backed non-metallic protective tape is applied to one of said sections along a socalled character or break zone or line in such manner that it adheres to one of said sections and affords a tapered outwardly opening pocket diverging from a surface section. Paint is sprayed or otherwise applied into said pocket as a layer inwardly terminating at the edge of the demarcation zone.
