FSR FIBERGLASS STAIN REMOVER is the best there is! FSR is a unique stain absorbing gel that serves a variety of purposes both ashore and afloat.
Ideal for removing oil, rust, exhaust, waterline and transom stains, yet can also be used anywhere fiberglass stains crop up (shower stalls, spas, furniture, etc.) Use for removing road soil from trailered boats and recreational vehicles.
Non-abrasive and safe to use on white painted surfaces as well as gel-coat.
Requires no sanding or compounding.
Simply apply with a brush, sponge or cloth; wait a few minutes, then wipe off or rinse.
Removes rust from stainless steel stanchions and railings.
Excellent for removing rust bleeders from the hull or deck.
Removes road dirt from RVs and trailer boats.
Test a small area first to be sure FSR will not damage finish.
Removes rust stains from clothing, sail cloth and other fabrics, too!
