Abstract

The invention relates to a process for producing a multicoat refinish, in which a metallic basecoat is sprayed on the prepared damage site and the adjacent regions of the old finish, so that it is opaque (hiding) in the region of the damage site and gradually runs out in the region of the old finish. Finally, a clearcoat is applied to the basecoat and, if desired, to the adjacent regions of the old finish. PA0 The process is characterized in that PA1 1. during the application of the basecoat composition to the adjacent regions of the old finish, the spraygun is inclined diagonally to the damage site, and PA1 2. during the application of the basecoat composition, a normal or only slightly reduced (3.0-4.5 bar) spraygun pressure is used.
