A process for producing a multicoat system on a substrate, in which a) an
electrodeposition coating film is deposited on the substrate, b) the
electrodeposition coating film is predried by heating to a predrying
temperature for a predetermined period, c) a coat of a surfacer is
applied to the electrodeposition coating film, and d) the
electrodeposition coating film and the coat of the surfacer are baked
together at elevated temperatures, and in which the predrying temperature
in step b) is equal to the temperature (T.sub.p) or lies above the
temperature (T.sub.p) at which the loss factor tan .delta., which is the
quotient formed from the loss modulus E'' and the storage modulus E', of
the unbaked electrodeposition coating material shows a maximum, and the
use of the resulting multicoat system.
