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 resistence and durability. The formula contains a new acrylic resin with properties until now impossible to obtain in a waterbased acrylic. The resistence hardness and covering power of Model Air is superior to any known acrylic for airbrushing. The pigments used for airbrush colours need to be ground to the finest possible consistency to avoid obstruction of the airbrush valves. The revolutionary milling process of the pigments used in the Model Air formula gives the modelpainter technical assurance and finest texture when applying the colours to the model and produces a very superior qualtity when applying the colours with a brush for miniscule details for washes and transparencies and layered application of diluted glazes. 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 excepcionally well to all surfaces. The adhesion of Model Air to resin models plastics steel and white metal is extraordinary.
