This set contains 6 acrylic paints that are each specially designed to represent different wood tones and to get several effects of old wood. Additionally, these paints can be used with a brush or an airbrush offering complete flexibility. They are water soluble which removes aggressive thinners and odors from our homes. This also makes thinning the colors very easy. In combination with Vol.2 (AKI 563) you can represent any type of wood. In order for the modeler to take full advantage and get the most out of these wood paint sets AK Interactive has issued a book "Realistic Wood Effects" (AKI 259) describing wood painting techniques.
