Metallic and pearl colors:
Apply one single coat, allow flash off until the coat is completely dried (matt). Apply a following lighter coat till covering is achieved. If necessary , finish with a mist coat by reducing the working pressure with 0.5 bar at the air inlet and increase the distance between spray-gun and object. 

Solid colors: 
Apply one full single coat. Allow flash off until the coat is completely matt. Apply another single coat and again allow this coat to flash off until matt, repeat until covering is achieved, a mist coat is not needed with solid colors.
Spot and fade-out repair:
Apply the basecoat in thin (overlapping) coats with the spray gun fully triggered at a spraying pressure of 1.5-1.8 bar until opacity is achieved. Allow to flash off until matt between coats, than fade out twice into remaining area (only metallic colors), using a spraying pressure of 1.5 – 1.8bar.
