To be honest, I have not run it with it on but, I have used it on a car for over 6 years and it has held up quite well. It has turned little white but am happy with the results. I would think with a wrap, since you have to wrap it tight, it would trap some amunt of moisture. With the techflex, it stays a little loose but it wont unwrap be cause its a tube, and being a little looser it will burn off any moisture rather quickly.
