Surplus bright aluminum from the paint industry. Although it is not paint, it has been coated with a solvent so it can be mixed into the vat to make paint, but the solvent has since mostly evaporated off leaving lumpy aluminum with a solvent smell. Ground in mineral spirits, we have tested it for use in rocket propellants, flares, HC smoke, ignition mixtures, etc.. It can also be used to make paint and lacquer as intended! Simply add one ounce per quart of lacquer for that metallic silver sheen.
