Natural earthy pigments for modelers Pigment DARK RED OXIDE 30 ml GSW 1761 Natural Earth Modeler Pigments are available in many different colors for a wide range of distinctive weathering effects for your models, including dust, rust, oil marks and dirt. Apply directly to a model, diorama, scale tank, airplane, model railroad, or battlefield with a pigment fixer to make them last forever. These pigments can be applied either dry or wet depending on what you want to achieve. Mix them with acrylic pigment fixer or Mud Effect to apply them wet. If you choose to apply the pigments dry, you can set them later with any acrylic pigment fixative. Other pigment fixers on the market, such as White Spirit or non-acrylic fixers, also work with our pigments, but are less recommended due to their strong odor and toxicity. These pigments are non-toxic, but inhalation of dust should be avoided. Contents: 1 bottle of 30 ml.
