A new method for the bonding of painted construction parts, in particular for the structural bonding of painted metals surfaces is described. In a first step of the inventive method, a carcase work adhesive is applied onto all parts of the oiled steel sheet on which later on, during assembly, bonding shall be performed. For the bonding, the lacquer layers on the carcase work adhesive are removed prior to the application of an assembly adhesive. Said method is simple and rugged. In comparison with the state of the art it is more economic, enables a highly structural and high strength joining with high torsional strength and a high ageing resistant compound quality.
