GLIPTONE's Medium Abrasive Grade Metal Polish is recommended for polishing and maintaining hard metals like stainless steel, chrome, nickel or magnesium. It will also tackle medium range corrosion, oxidation, tar, rust, stains and tarnish from aluminum, brass, copper and bronze with the greatest of ease. NOTE: this polish contains no ammonia, acid or water. Consequently, GLIPTONE metal Polish applies and removes easier and goes twice as far as equal amounts of any other metal polishes. GLIPTONE Metal Polish seals and protects with penetrating oils and polymer sealant for a long lasting brilliant shine.
