The range of auxiliary products has been formulated to modify the characteristics of a color. Our selection can be divided between mediums which change the transparency or the shine of a color, or to reproduce the natural effect of chipped off paint, or employed to fix decals on the model, and varnishes, both acrylic and polyurethane, which unify the finish of the models or figures and provide a protection and additional resistance to manipulation. Our airbrush mediums are used as much to dilute a color as to delay the drying of paint in the airbrush and the different cleaners are employed to assure the best maintenance to the working tools of the modeler, be it brushes or airbrushes.
