Superior bonding strength and elasticity

TotalBoat Polyester Structural Marine Repair Putty is a tough, resilient resin mixed with long strand milled glass fibers to provide resilience, maximum impact resistance and elasticity so it won’t crack as it ages. It’s ideal for marine applications where high-strength structural bonds are critical, including:

• Bonding the deck to the hull
• Bonding stringers to the hull
• Bonding the liner to the hull
• Bonding and filleting bulkheads
• Tabbing in the fittings
