Abstract: A process for producing a gravel-impact-resistant multicoat lacquer finish by cathodic electrodeposition of a primer on an electrically conductive substrate, subsequent application of a primer surfacer coat of an aqueous paste filler that contains one or several water-dilutable binders that are curable at temperatures up to 180.degree. C., with subsequent application of one or several base coats and finishing coats. To produce the primer surfacer coat, an aqueous paste filler is used that contains 0.1-20 wt % polyamide powder, polyacrylonitrile powder or mixtures thereof with particle diameters in the range 0.1-100 .mu.m, wherein the high-solid value of the aqueous paste filler is not less than 75 wt %.
