This set contains the four colours that are indispensable for painting the cockpits and other inner surfaces of US aircraft from the World War Two period, including the Army Air Force, Navy and Marine Corps machines. AKI's Real Colors are the highest quality acrylic lacquer paints, made from a chemical formula that is improved over other brands in the market. They spray through an airbrush in a silky smooth manner, and adhere to the surface and dry perfectly with a soft satin finish. These paints work superbly with all kind of weathering or masking products. They may be diluted with AK-Interactive's specific thinner or thinners from other manufacturers that are intended for acrylic lacquer paints (non-vinyl). They may also be easily mixed with other acrylic lacquer paints. Real Colors accurately reproduce the original colours.
