3M Marine Aluminum Restorer and Polish 18 oz
For pontoons and aluminum boats. Designed to remove oxidation growth and stains and restore a lustrous appearance to bare aluminum. Also removes heavy oxidation and restores shine to most painted aluminum surfaces. We recommend testing on small inconspicuous painted areas to determine suitability. If too aggressive for your painted aluminum, use 3M Marine One Step Painted Aluminum Cleaner and Wax. Not recommended for anodized coated aluminum.
