Here is an example of our product, Official Orange, being used on worn metal. In this situation it was a brass plate, which clearly had some surface damage. Choosing your tool to agitatate depends on the level of damage, in this case we used #0000 steel wool. With just a single spray of a 15-1 mix, and a little elbo grease, the surface damage was removed. In metal restoration you can't fully bring the surface back 100% withwithout adding multiple steps, but using Official Orange will prevent aging metals from becoming such an '"eye-sore."
