Vallejo model color paints are a water-based formula designed with the highest pigment concentration. Vallejo is a brand known for their high quality and wide range of colours, including shades such as metallic, matte, and shades from historical periods such as WWII. These paints have been designed for use with a paint brush but can be used with an airbrush due to their properties. Alternatively, we have Vallejo model air paints, which are specifically made for airbrushes.
