Clearcoat paint composition for wet-in-wet application before stoving

The invention relates to a method for enameling substrates with a coloring and/or effect-giving base enamel and clear enamel coating. According to said method, a coloring and/or effect-giving base enamel layer from a base enamel coating compound is applied to a substrate and then given a clear lacquer coating using the wet-on-wet technique. The non-hardened clear enamel layer is exposed to high-energy radiation before being baked with the base enamel coating. The clear enamel coating compound used is one with a resin solid comprising 50 to 98 weight per cent of system A, which can be cured thermally by addition and/or condensation reactions and which is essentially free from radically polymerizable double bonds and essentially free from groups which also react with radically polymerizable double bonds of system B, and 2 to 50 weight per cent of system B, which can be cured by radical polymerization of olefinic double bonds during exposure to high-energy radiation. The weight per cent values total 100 weight per cent and the C=C equivalent weight of the total resin solid of A and B is between 300 and 1000.
