Collinite NO. 850 Metal Wax is an easy-to-use polish that restores, shines, and protects in one single operation. Removes mild rust, salt deposits, and heavy accumulation of film brought on by time and weathering. Leaves behind a radiant, durable protective coating that guards against future pitting and corrosion. For use on tarnished or lightly rusted metal (non-coated and non-painted). Exclusively for marine and aeronautical detailing; not for anodized aluminum or household use.
