TotalBoat Polyester Structural Repair Putty – Marine Grade Long Strand Fiber Fiberglass Reinforced Filler for Boat and Automotive Repair

Customers find the marine repair putty works well for filling gaps and holes, with good adhesion and strength that prevents cracking and flexing. The product is easy to work with, spreads smoothly, and is very easy to mix, with one customer noting it sets up in a couple of hours. While many find it easy to sand, one customer mentions it becomes quite hard to sand after 24 hours. Customers consider it well worth the money, noting it's cheaper than epoxy.
