Davis FSR Fiberglass Stain Remover Large (2 liters)

Davis FSR Fiberglass Stain Remover is a concentrated marine cleaning gel designed to remove stubborn stains and discoloration from fiberglass, gelcoat, and painted surfaces. Its thick gel consistency stays where it is applied, making it especially useful on vertical surfaces, boat hulls, transoms, and waterlines where liquid cleaners can quickly run off.

FSR helps eliminate difficult rust stains, waterline stains, exhaust stains, mineral deposits, and other marine-related discoloration without the need for aggressive abrasive scrubbing. Simply apply the product to the stained area, allow it to work according to the manufacturer's directions, and rinse thoroughly.

Because it is non-abrasive, FSR is an excellent choice for cleaning stained fiberglass and gelcoat without relying on heavy compounding or sanding. It is particularly useful for restoring the appearance of boat hulls after extended exposure to the water and marine environment.
