Thanks for all the input. I'll try using a hair dryer first to avoid any extreme heat. If that doesn't work then I'll break out the heat gun. The felt and cotton gloves sounds like a wise approach. I just have to wait for a break in these North Carolina thunderstorms that keep rolling through. I'll put up a post when I'm done and let you know how it worked.
"From what I know, you can expect the fabric to fail before the Makrolon. Or the thread, They recomend using the thread that doesn't rot, it also is expensive but lasts a couple of times longer than regular thread. Depending on the climate I would expect it to last at least 2 times longer. I hope to get at least 5-7years out of it before replacing it here in Florida. I know some say it will last longer, I hope so, we shall see."
This doesn't quite clarify it for me. With Stratglass the thread fails first and at least in Viginia, we get 7-8 years out of dodger windows if well cared for, as much as 15-20 years if kept covered. When I last replaced mine (not covered, 8 years) it was not because of clarity but stiffness... but Lexan is effectivly rigid anyway.
