A process for multilayer repair coating, comprising the following steps: applying a first base coat layer of a conventional, water-borne base coat I containing at least one special effect pigment, applying a second base coat layer of a water-borne base coat II onto the resultant coating, wherein the water-borne base coat II for producing the second base coat layer is feathered out into the zones bordering the repair coating, and wherein this water-borne base coat II comprises

Process for the production of a multilayer vehicle repair coating

The present invention relates to a spot repair finish process for refinishing substrates, in particular vehicle bodies or parts thereof, wherein a very good quality finish is produced with virtually no differences, such as in color shade or overspray margins and edge marks, visually perceptible between the old finish and the repair finish. The spot repair process of the present invention works especially well with pigmented coatings of critical color shade, in particular with specific light color shades.

Process for refinishing substrates

A process for the multi-layer repair coating of substrates, wherein a base coat layer of a water-based base coat coating composition is applied to a precoated substrate and a clear coat layer of a transparent clear coat coating composition is applied to the base coat layer thus obtained, characterised in that the base coat layer of the colour- and/or special effect-imparting water-based base coat coating composition is applied in three successive spray passes, and each spray pass is executed such that uniform, adjacent and substantially non-overlapping coating strips are applied to the substrate surface to be coated.
