Keep your running gear clean and performing at its best. PropCoat Barnacle Barrier is a specialized antifouling coating engineered for underwater metal surfaces — propellers, shafts, trim tabs, and outdrives. It forms a durable, slick barrier that prevents barnacles, algae, and marine growth from bonding to metal, so your prop stays smooth and your boat stays efficient season after season.
Compatible Applications
- Propellers (aluminum and stainless steel)
- Propeller shafts
- Trim tabs
- Outdrives and lower units
- Rudders and other submerged metal hardware
Key Features
- Bonds to bare and painted metal surfaces
- Resists barnacle and marine organism adhesion
- Maintains propeller efficiency and reduces drag
- Long-lasting protection through the boating season
- Designed for use on aluminum, stainless steel, and bronze
Parts Desk Insights
Best used as a seasonal treatment applied at haul-out or before launch. PropCoat is the go-to choice when you want targeted protection on running gear without applying full hull antifouling paint to metal components. Pair it with a Pettit Zinc Coat Barnacle Barrier Spray for broader underwater coverage, or add a MerCruiser Alpha One Gen II Zinc Anode Kit to complete your corrosion protection system. Surface prep is critical — apply to clean, dry, bare or lightly sanded metal for best adhesion. Reapply each season or as needed based on fouling conditions in your area.
