Abstract: Described herein is a method for treatment of a metallic surface, including the step of (A) contacting the metallic surface with a first aqueous composition, and a subsequent step of (B) contacting the metallic surface subsequent to step (A) with a second aqueous composition. Also described herein is a kit-of-parts including the first and second aqueous composition and a kit-of-parts including master-batches of the first and second aqueous compostions. Also described is a method of using the kit-of-parts for treating a metallic surface and substrates including the thus treated metallic surfaces.
