- Multicoat paint systems are preferably applied according to the so-called "basecoat-clearcoat” process, i.e. a pigmented basecoat is pre-coated and, after a short flash-off time, without a baking step (wet-on-wet process), overcoated with clearcoat. Then the basecoat and clearcoat are baked together.
