Davis Instruments FSR Fiberglass Stain Remover Gel - Available in 16 oz and 2 Liter Big Job Size

Davis Instruments FSR (Fiberglass Stain Remover) is a stain-absorbing gel formulated to lift oil, rust, exhaust soot, waterline rings, and transom stains off fiberglass without sanding or compounding. Simply apply the gel to the stained area, let it sit for a few minutes, then wipe off or rinse away to reveal a clean, restored surface. FSR is safe for gel-coat finishes and white painted surfaces alike, making it a go-to solution for hull sides, transoms, swim platforms, and fiberglass decks that have picked up stubborn discoloration over a season on the water. The alcohol-based, biodegradable formula is unscented and made in the United States, giving you an effective marina-safe cleaner without harsh fumes.

Sizes & Options

The 2 Liter Big Job size delivers roughly 4x the volume for full-hull detailing, larger vessels, or fleet and marina maintenance where multiple stained areas need attention. Choose based on hull size and how much stained surface area you need to cover in a single application.
