When I got the boat, the tubes were painted white, and the bottoms of the tube where they water sprays from the hull and flaked off. The tubes also had a fair amount of UV damage and pinhole leaks. The tuff coat product has been on since September and was outside in the cold and the snow. I didn't notice anyproblems. The boat is coming back up from Miami in April, I will send some pictures on how it looks. For my application, tuffcoat was the right solution, as the only other option would have been to replace the tubes.
