DAVIS FSR FIBERGLASS STAIN REMOVER
Davis Fiberglass Stain Remover (FSR) is a unique stain absorbing gel that serves a variety of purposes. It is ideal for removing oil, rust, exhaust, waterline and transom stains. This product also works great on shower stalls and furniture made of fiberglass.
Its non-abrasive quality means that it is safe to use on white painted surfaces as well as on gel-coat. Just don't forget to test a small area to be sure FSR will not damage the finish. This product requires no sanding or compounding, and can simply be applied with a brush, sponge or cloth. Wait a few minutes and then wipe or rinse off.
