A process for repairing a vehicle coating, comprising the following steps: I) applying a UV radiation coating composition onto a coated vehicle or vehicle part, having a blemished area on the coated surface to be repaired, wherein the coating composition comprises A) at least one free-radically polymerizable oligomeric and/or polymeric binder containing olefinically unsaturated groups, B) optionally, at least one free-radically polymerizable monomeric reactive diluent containing one or more olefinically unsaturated groups, C) at least one photoinitiator, D) at least one metal compound of a metal salt containing the metal in the cation and/or anion of the compound, organometallic compounds, metal coordination compounds and mixtures thereof, wherein the metal is from groups 13-14 of the periodic system of elements and a transition metal, and is able to occur in at least 2 oxidation states other than zero and E) optionally, water, organic solvents, pigments, fillers and/or conventional coating additives, and II) irradiating the resultant coating with UV radiation.
