Our Leverage Metal Serum is formulated to produce a crystal clear shine that provides UV protection while repelling fingerprints and water spots. The Leverage Metal Serum will bring life back to any piece of chrome, aluminum and stainless steel surface. We have used it on many wheels, pontoons, trailers and trim. You will enjoy the difference and compliments that you will receive after using our Leverage Metal Serum. It is very simple to apply with two terry cloth towels. Start with shaking the bottle to activate the serum. Apply the serum to a dry terry cloth towel then lightly apply to the surface. You will rub the surface briefly until you see a black residue then use your second towel to wipe off the excess serum.
