Vallejo Premium Colour Paints are a range of water-based, non-toxic airbrush-ready paint, suitable for all surfaces. They are specially formulated for adhesion to metals, fibreglass, polyethylene, clear Lexan polycarbonate, slot car and most RC car bodies. Once protected with varnish, Vallejo Premium can be overpainted with oil-based enamels or oil colours: they can stand cleaning with turps and even alcohol. The formula is non-toxic and low odour.
