I made snap-on covers for all of my Lexan. I had 2- 3/4" Lexan Hatches and my dog-house had 2 pieces of 3/4" Lexan. I had covers for all.

My storm windows were also 3/4" Lexan. I only had them over my windows at sea. I didn't bother covering them.

I agree with delmarrey, heating them could cause more harm than good. However, I never had any crazing so I didn't have to deal with it. However, I did help a friend reseal his Lexan windows. They were crazed and when we took them off, they fell apart.

My understanding is, once Lexan has crazed, it is extremely degraded. Plexiglass is a little less because it isn't tempered and crazing is only surface and can usually be polished out. IMO, plexiglass is a better option than Lexan, if it is going to be exposed to the Sun over long periods of time. Understanding, of course, that Lexan is much stronger, when new.
