Abstract
A process for multilayer coating of a metal substrate includes pretreating the metal substrate with an acidic aqueous composition comprising phosphate ions and/or a water-soluble titanium and/or zirconium compound, and water. The pretreated metal substrate optionally is flashed off and a surfacer layer of an organic-solvent based surfacer coating composition is applied. The organic-solvent based surfacer coating composition includes a polyaspartic acid ester, a polyisocyanate cross-linking agent with free isocyanate groups, a pigment and/or extender, and an organic solvent. The surfacer layer is cured.
