Vallejo Model Air Colors - Mahogany (17 ml) Model Air is a range of liquid acrylic colours developed especially for airbrush techniques, with very finely ground pigments and an acrylic resin with properties of extreme resistance and durability. Colours can be mixed with one another, diluted with water, Model Air Thinner or Varnish, according to the effect desired, but we recommend the use of Model Air Thinner since this product conserves the properties of the colours. Model Air adheres exceptionally well to all surfaces. The adhesion of Model Air to resin models, plastics, steel and white metal is extraordinary. Once protected with varnish, (Gloss, Matte or Satin) Model Air can be overpainted with solvent based enamels or oil colours: they withstand cleaning with turpentine and even a light wash with alcohol. The resistance to abrasion of the colours, once varnished, is superior to any other waterbased acrylic. Model Air Colours are supplied in a 17 ml. bottle with eyedropper. This packaging prevents the paint from evaporating and drying in the container.
