Marine Nano Shop MineralX Stain & Water Spot Remover
Marine Nano Shop MineralX removes mineral stains and water spots from gelcoat and marine paint. Tap water and salt leave deposits in the pores. This is the decon step before you prime and coat.
Work a cool panel. Wipe clean. On glass, use it before 20/20 polish. It is in the New Boat and Restoration kits for a reason: coatings do not stick to mineral film.
