Abstract
A method of forming a composite coating having a polychromatic effect over a substrate is provided in which a first liquid basecoat material is exposed to air having a temperature of about 50.degree. F. to about 90.degree. F. (10-32.5.degree. C.), a relative humidity of about 40% to about 80% and an air vilocity of about 20 FPM to about 150 FPM (0.10-0.76 m/s) at the surface of the first basecoat material for a peroid of about 10 to about 180 seconds. A second liquid basecoat material comprising effect pigment is then applied over the set first basecoat material by a bell applicator to produce the composite coating.
