Model Color is Vallejo's main line of brush-applied acrylic paint. Originating from Spain, Model Color is specially formulated to adhere to plastics and polyesters. It is intended primarily for hobby detail painting, of which many colors have Federal Standard, RAL, and RLM equivalents. Formulated for smooth and uniform coverage, it has a superior leveling quality eliminating visible brush strokes. Colors may be diluted with thinners or Mediums and can be thinned for airbrush use as well. The formula is non-toxic and low odor. Brushes may be washed clean with ordinary tap water.
