This set includes the four colors that are indispensable for painting models of the British aircraft used during World War One. Included are two variants of the PC10, the PC12, and the Battleship Grey colour that had been commonly used for painting the metal panels. Our paints are not only historically accurate and specially formulated with top quality components; they also have been designed taking into account the scale reduction effect.*Our acrylic paints are ready to use straight from the bottle; simply shake, and the paint is ready to go. Dilution is not necessary when airbrushing AK acrylic paints; however, when painting camouflage or fine lines, add a few drops of our specially formulated thinner AK11500. Useful for all acrylic paints, the AK11500 improves the performance of the paint and is vastly superior to most other available thinners, resulting in a greater degree of coverage when applied by brush. This set contains:AK11158 PC10 Early (Reflective Green)AK11809 PC10 LateAK11810 PC12AK11163 Battleship Grey (Intermediate Blue) *A model aircraft reflects less light than an actual full size aircraft; this means the color applied to the model must be of a lighter shade to look the same as the full sized version. If the same color tones were applied to each, the model would appear darker as it reflects less light.
