Autowave 3 step Special Effect Colors (SEC) provide unique color and flip/flop effects when viewed from different angles. The special characteristics of these colors require that they be pre-packaged as ready mix colors. Autowave Special Effect Colors are designed for custom finishing and are normally applied over a black foundation coat, followed by Sikkens clearcoat for protection and durability. In some cases these colors are also required to match recent special option OEM colors and may be required as part of Autowave formulas.
