Great for brush painting or air-brushing, Tamiya acrylic paints are made from water-soluble acrylic resins that clean with plain water . These paints can be used on styrene resins, Styrofoam, wood, or any common model plastic. The paint covers well, flows smoothly, and can be blended easily. The XF series of colors has a lusterless matte finish perfect perfect for military modeling. When thinning for air brush, Tamiya recommends their X-20 Acrylic Thinner, or their Lacquer Thinner for faster drying times and a harder finish.
