Revell Colour is a synthetic resin enamel that doesn't harm the plastic surfaces of model cars. This 14ml bottle, favored by many hobbyists, can also paint various other materials. All colors, except the signal color, can be mixed and thinned using 'Revell Color Mix'. This allows application with a brush or airbrush, using 'Revell Painta Clean' for brushes and 'Revell Airbrush Clean' for the airbrush.
