A fluid to enable you to simulate worn and scratched surfaces on scale models. It is odourless and water soluble, and a great (less messy) replacement for the traditional "hairspray" technique. To use, apply 2 or 3 coats by airbrush over a painted surface. As soon as it is dry, apply the final coat over the top. Once that is dry, dampen the top coat slightly, then use a stiff brush, toothbrush, cocktail stick etc to scratch and chip the surface and achive the look you need. Supplied in 35ml bottles.
