Effortlessly removes water line stains by applying a small amount of Pristine Marine Gel Coat Rust and Stain Remover and the stain will magically disappear. To make it easier for in water boats to stay alongside the hull while cleaning from a dinghy, you can use a specially designed handle with suction cups to hold yourself close to the boat.
In addition to attacking waterline stain, use Gel Coat Rust and Stain Remover solution for dissolving rust. Remove rust stains from the hull and deck, safe to apply not only to gel coat, but also to metal, painted surfaces, and even our synthetic non-skid. Apply, let sit for awhile, and then rinse thoroughly with water. For stubborn rust, a second application may be needed, or a little soft-bristle scrubbing. For hard to reach deck areas like those around the bases of stanchions, use a toothbrush to coax the gel into the areas.
*You will need to wear gloves, avoid coming into contact with the product, and be careful of the fumes. *You will, of course, need to re-wax the hull after applying these products.
