Abstract: A two-tone painting method includes applying a powder primer to a substrate, followed by a powder basecoat applied dry-on-dry onto the powder primer. The powder basecoat is preferably applied in the same painting booth as the powder primer, i.e., without curing the powder primer. The powder basecoat includes a flake additive, such as a mica flake or a metal flake, which prevents surface irregularities from forming in the powder primer and the powder basecoat as a result of not curing the powder primer before applying the powder basecoat. The substrate is then masked, and a second basecoat is applied. The masking is then removed and a clearcoat is applied. The second basecoat and the clearcoat are then cured simultaneously in an oven.
