Note:
If the existing finish is not compatible, 2K primer surfacer should be used as a sealing layer before applying the basecoat otherwise there may be problems such as lifting,peeling,blistering ,flooding,etc.
At temperature over 30°C or in high humidity, it is recommended to use N&D Retarded Solvent to avoid mottling.
Because of the high transparency of metallic basecoat, the primer surfacer shoulder be in consistent color and flat without any sand scratches,grain,or unevenness so as to prevent defects of mottling, poor metallic effected.
To avoid problems of mottling or poor adhesion, the metallic paint film should not be thicker than 25 um.
Better effect could be achieved if the extra silver powder could be removed with dishcloth after coat every layer and flash dry.
