Tamiya Enamel Paints are used for brush or spray painting, and can be applied to almost any surface of wood, metal or plastic. When spray painting enamels, best results are achieved by adding 2 parts of thinner to 10 parts of paint. X designated colors have a glossy finish while XF designated colors are flat finish. The paint can be thinned for airbrushing using Tamiya X-20 Enamel thinner. The paint can be also thinned for airbrushing using Tamiya Lacquer Thinner. Using Tamiya Lacquer Thinner will yield faster drying results and a harder finish. For better paint brushing results use Tamiya Paint Retarder (87114) for a smoother brushstroke free finish.
