This set contains 6 acrylic paints essential for painting any grey figure or spaceship model, making the proper shop transitions between the shades to achieve a realistic look. They can be applied by brush, taking advantage of the 3rd generation high coverage and adhesion. When diluted with dedicated thinner, they can be airbrushed as easily as lacquer-based paints.
