Abstract
The invention relates to a process and an apparatus for applying two or more colors of paint by applying a first paint to at least part of a substrate, followed by a second and, if desired, further different-colored paints to different parts of the substrate and hardening the applied coats of paint by baking, which comprises applying the second and if desired the further different-colored paints without interim baking of the first paint to the preselected different parts of the substrate using electrostatic atomization at stationary atomizer edges involving transport of the paint particles in an electric field and, after the first and subsequent paints have been applied, hardening all coats of paint together by baking.
