Rustin’s Burnishing Cream Use the burnishing cream to achieve a mirror like finish and final polished surface. Can be used 24 hours after applying the Rustins Plastic Coating. To apply make sure the surface is smooth and hardened. Once hardened rub the surface with very fine wet and dry paper until all imperfections are removed. If surface becomes scratched rub down until marks disappear and burnish. If an electric buffing machine is used add water to the cream to prevent from drying too quickly. Available in small 63ml.
