摘要

Process for partially coating metallic workpieces, already coated with an electrically conducting lacquer, comprises completely or partially removing the lacquer (12) in the regions (16) to be coated, and subjecting the workpiece to a cathodic electro-dip lacquering on the regions to be coated. Preferred Features: A resistance of the electrically conducting lacquer produced above its layer thickness and a layer thickness of the new lacquer is adjusted above a height of an applied voltage during electro-dip coating.
