TotalBoat Marine Gelcoat For Cosmetic Repairs
The TotalBoat 14409 marine gelcoat is a premium marine-grade polyester formulation designed for cosmetic gelcoat repair, hull coatings, and exterior finishes on boats and other fiberglass parts. Its high-viscosity, non-sagging formula provides strong adhesion and good coverage, suitable for buffing to a showroom finish after curing. The gelcoat can be tinted with polyester resin or gelcoat colorants to match surrounding areas, including pastel whites when tinting white gelcoat. A MEKP-catalyzed curing process yields a durable surface that sands and polishes to a high-gloss finish at typical room temperatures.
Globalcom Fiberglass Repair Kit With Color Match
This multifunctional kit from Globalcom addresses chips, cracks, pits, gouges, scratches, and holes across a range of watercraft. It includes a white base color plus four color pastes (blue, brown, maroon, black) to achieve an exact color match. After curing, the repair is UV-resistant and waterproof, with strong adhesion to fiberglass surfaces. The kit emphasizes ease of use and long-lasting performance in harsh marine environments, making it a strong all-around option for both repairs and color-matching projects.
Marine Coat One Gel Coat White With Wax
Marine Coat One offers an ISO/NPG gel coat in white with wax and six tinting pigments (white, black, yellow, blue, red, brown). The kit provides a straightforward approach to color matching: tint white gel coat with pigment pastes before adding MEKP catalyst to initiate curing. The wax content supports a tack-free surface, and the included catalyst ensures a hard, showroom-ready finish upon curing. The formulation is designed for durability in marine conditions and is suitable for repairing scratches, gouges, and cracks on fiberglass surfaces.

Buying Guide: Gel Coat Repair Kit Purchase Considerations
- Color matching capabilities: Look for white bases with multiple tinting pastes to accurately blend repairs with your boat’s gel coat.
- Durability and UV resistance: Choose kits that offer strong adhesion and UV protection to withstand sun exposure and harsh marine environments.
- Gloss finish and sanding: Ensure the kit cures to a gloss that is easy to sand, buff, and polish for a showroom-like appearance.
- Ease of use: Consider kits with clear mixing ratios (1:1 or similar), simple cleanup, and guidance for brush, roller, or spray application.
- Curing time and temperature: Pot life and full cure times can vary; plan repairs for typical ambient temps and avoid extreme conditions.
- Safety and environmental impact: Prefer formulations that are safe for users and minimize environmental concerns, especially for aquatic environments.
- Application surface and compatibility: Verify compatibility with fiberglass, hulls, decks, and composite parts; some kits are better suited for above-waterline repairs.
- Inclusion of catalysts and pigments: Check whether MEKP or other catalysts are included and if tinting pigments cover a broad color range.
- Repair scope: For small chips and scratches, lighter-duty gel coats may suffice, while deeper gouges may require high-fill epoxy fillers for structural integrity.
- Accessibility: Availability through major retailers and reasonable shipping options can influence decision-making for regular maintenance kits.
