TotalBoat TotalBilge Marine Epoxy Bilge Paint – White Gallon
Best for large bilge spaces and bulkheads, this white gallon provides a tough, waterproof epoxy coating that resists chemicals, oils, acids, alkyds, and solvents. The coating is hard-wearing and suited for engine rooms, lazarettes, lockers, and storage compartments. It offers strong coverage and brightens bilges for easy inspection of leaks or dropped items.
- Application: 1–2 coats by brush, roller, or spray on prepared fiberglass, wood, or metal.
- Priming: Metals with TotalBoat TotalProtect; fiberglass can be primed with TotalProtect if desired; wood can use TotalBoat Topside Primer if desired.
- Best for: Large bilge areas and bulkheads that benefit from a bright, reflective finish.
Caution: Ensure proper ventilation during application and curing. Heavy-duty use may require additional coats for maximum durability.
TotalBoat TotalBilge White Quart
Best for small to mid-size bilge areas requiring a precise white finish, this quart balances coverage with ease of handling. It shares the same chemical resistance and ease of use as the gallon variant, making it a good option for touch-ups or smaller boats. Best for boat owners who want a consistent white bilge color with straightforward application.
- Best for: Small to medium bilges and lockers that need bright visibility.
- Hint: Pair with appropriate primers for fiberglass for best adhesion.
- Caution: Might require multiple thin coats for fully uniform coverage in very chalky or porous surfaces.
TotalBoat TotalBilge Gray Quart
Choose gray for mid-sized bilges where a neutral finish reduces glare and helps key areas recede in the overall workspace. This gray option provides the same waterproof epoxy properties as white variants, with strong solvent and chemical resistance for engine rooms and storage compartments. It’s better for installers who prefer a subtler bilge look while maintaining high visibility of potential leaks.
- Best for: Mid-sized bilges and areas where a non-glare finish is beneficial.
- Application tip: Use 1–2 coats on prepared surfaces for even coverage.
- Caution: Gray tones may show dirt differently than white; cleaning frequency can impact appearance.
TotalBoat TotalBilge Gray Gallon
Best for larger bilge spaces, this gray gallon provides comprehensive coverage with the durability required in busy engine compartments. The epoxy coating resists common bilge contaminants and remains relatively easy to apply in multiple coats. Select this when you need a robust, uniform gray finish over extensive areas.
- Best for: Large bilges and bulkheads where a durable gray finish is preferred.
- Note: As with other TotalBoat Bilge Paints, proper surface prep yields the best adhesion and finish.
- Caution: Darker colors may require more attention to maintaining a uniform finish in very bright light conditions.
Interlux YMA102 Bilgekote – White Quart

It is a quarterly option that supports tight spaces and areas requiring a clean, professional look. This product is selected for buyers who want a legacy marine-grade solution with proven performance in bilge environments.
