Photo-etched, aluminum, die-cast and other metal components can add great detail to your plastic model, but special care is needed when painting them - this product has been developed to aid in that process. Use it as a primer coat on metal components for a true topcoat and prevention of peeling. Causes no damage to plastic parts, freeing you up to use it on parts which are already attached to the model. Can be sprayed on via airbrush if so desired. Cap features a handy applicator brush.
