ABSTRACT:
This invention is directed to an improved method of coating a substrate. The improvement includes applying to the substrate a rinse composition which contains one or more surface energy-modifying compounds. The invention is further directed to an improved method of producing weldable parts and the parts prepared by this method. The invention is especially useful for automotive parts using weldable pre-painted metal substrates to which are applied essentially zero VOC powder coatings.
