The Vallejo Primers series offers primary paints that dry quickly, preserve the small details of the surface and distribute evenly. Their use has been suggested before starting painting as they improve the adhesion of the applied paint. It can be used directly or diluted with Airbrush Thinner or Flow Improver for painting with Airbrush gun (recommended pressure 15-20 psi). The paint can be cleaned with Airbrush Cleaner.
