The invention relates to a method for producing a multilayer coating on a substrate, whereby: a) an electro-dipcoat film is deposited onto the substrate; b) the electro-dipcoat film is predried for a predetermined period of time by heating it to a predrying temperature; c) a layer of a filler is applied to the electro-dipcoat film, and; d) the electro-dipcoat film and the layer of the filler are baked together at increased temperatures. The predrying temperature in step b) is the same as temperature (Tp) or is greater than temperature (Tp), at which the dissipation factor tan delta , which is the quotient from the loss model E and storage module E', of the electro-dipcoat that has not yet been baked indicates a maximum. The invention also relates to the use of the resulting multilayer coating.
