Matt acrylic paints, water-based and specially formulated for airbrushing. The Model Air color palette includes a comprehensive selection of military colors used throughout recent history, from World War I and II to the present day. Each color is based on extensive research by our experts into existing and historical military references, providing modelers with the highest possible historical accuracy. Model Air can be used directly or thinned with Vallejo Airbrush Thinner or Flow Improver. It is recommended to first prime the surface and then apply Model Air in several layers. The colors dry very quickly and form a homogeneous film of exceptional durability, while preserving even the smallest details of the model. For airbrushing these colors, a compressor air pressure of 15 to 20 PSI or 0.5 to 1 kg is recommended. Model Air can also be applied with a brush. For proper maintenance of the airbrush, we recommend using Vallejo Airbrush Cleaner.
