Davis FSR (Fiberglass Stain Remover) is a unique stain absorbing gel that is ideal for removing oil, rust, exhaust, waterline and transom stains. Its non-abrasive quality means that it’s safe to use on white painted surfaces as well as on gel-coat. Just be sure to test a small area first to be sure FSR will not damage finish. Requires no sanding or compounding. Simply apply with a brush, sponge or cloth. Wait a few minutes and then wipe off or rinse.
Beside fiberglass, can also be use on any stain on shower stalls, furniture, road soil from trailered boats and recretional vehicles.
