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, including shades from World War I, World War II, and up to the present day. Each color is based on extensive research by our experts into existing and historical military references to provide 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 multiple layers. The paints dry very quickly and form a homogeneous color film of exceptional durability while preserving even the smallest details of the model. For airbrushing these colors, a compressor pressure of 15 – 20 PSI or 0.5 to 1 kg is recommended. Model Air can also be applied with a brush. For proper care of the airbrush, we recommend using Vallejo Airbrush Cleaner.
