Star brite GEL FSR Xtreme Fiberglass Stain Remover – 16 oz (205216)

Restore your boat’s shine with the Star brite GEL FSR Xtreme Fiberglass Stain Remover, a powerful, professional-grade solution designed to eliminate tough stains without sanding or scrubbing. This advanced gel formula targets rust, tannin, and waterline stains, delivering fast, effective results on fiberglass, gelcoat, and painted surfaces.

The thick, clinging gel stays in place on vertical and curved areas, allowing deeper penetration and superior stain removal. Ideal for marine and RV use, this easy-to-apply cleaner activates in minutes—simply apply, wait, and rinse for a like-new finish. 

Perfect for hulls, decks, and other fiberglass surfaces, Star brite FSR Xtreme reduces scrubbing effort while preparing surfaces for waxing or polishing.

Key Features:

• Stain-Specific Targeting: Effectively eliminates tough organic and metallic stains, including rust streaks, tannic acid (tea-colored stains from leaves/wood), and the common brown waterline "mustache" caused by brackish or polluted water.

• Surface-Safe Formula: Designed for use on fiberglass and gelcoat, it is also safe for most painted finishes. It cleans deep into the pores of the gelcoat to prepare the surface for a fresh coat of wax or ceramic protection.

• No-Sanding Required: The chemical action does the heavy lifting, preventing the micro-scratches and surface thinning that can occur with abrasive pads or rubbing compounds.

• Fast-Acting Dwell Time: Once applied, the formula activates in just 2–3 minutes, breaking the bond between the stain and the surface for a simple "rinse-away" finish.

• Removes rust, tannin, and waterline stains quickly and effectively

• No sanding required – safe on fiberglass, gelcoat, and painted surfaces

• Thick gel formula clings to vertical surfaces for better performance

• Fast-acting – works in minutes to break down tough discoloration

• Easy application with cloth, sponge, or brush

• Prepares surface for polish, wax, or ceramic protection

Directions for Use

1. Apply: Using a cloth, sponge, or brush, apply a generous layer to the dry, stained area.

2. Wait: Allow the gel to dwell for 2 to 3 minutes. For vertical surfaces, the gel's "xtreme" viscosity ensures it stays in place rather than running off.

3. Rinse: Rinse thoroughly with fresh water. For extremely old or stubborn rust, a second application may be required.

Applications:
Boat hulls, decks, transoms, RV exteriors, and other fiberglass or gelcoat surfaces exposed to harsh environments.

Trusted by marine professionals, Star brite delivers high-performance cleaning solutions designed to maintain and protect boats, RVs, and outdoor equipment in demanding conditions.

Installation Tip: While safe for most surfaces, always spot-test a small area if you are applying near vinyl decals or anti-fouling bottom paint. For the best results, use this as a "prep" step before applying Star brite Premium Marine Polish to seal the pores and prevent the stains from returning.
