Autosol Marine Shine is made to clean, polish and protect beloved metal on boats (e.g. stainless steel fittings) and fibreglass surfaces. It uses a mild abrasive rubbing agent, ideal for restoring shine to weathered surfaces. The 10x concentrated paste formula removes stains, rust, tarnishing with ease. The paste leaves a thin surface wax with UV inhibitors that delays future tarnishing and corrosion.
