These filters are specially designed for use on any Panzer Grey German vehicle from WWII; but also on aircraft, robots or any other dark grey surface. Use the filters by moistening a brush and applying it without flooding the surface, to enrich hues in your models, unify camouflage, or highlight areas with a different tone. With these products we will avoid mixing paints, looking for the correct dilution, or searching for the correct colors for our vehicle. These filters are enamel based and can be cleaned or diluted with Odorless Enamel Thinner. 30 mL jar.
