The Army Painter has developed The Warpaints: Airbrush Medium to enable our superior quality Warpaints to be used with an airbrush. This Airbrush Medium which comes in a large 100ml bottle is highly versatile, and any high-quality acrylic paint will benefit from it. A real quality of this product is that the Airbrush Medium not only works as a thinner for acrylic paints - but also as a flow improver!
