Thats a good film. I carry it also, among others. It's a high performance film. I think there may be alot of factors in film working on acrylic or lexan. The main factor is heat. If your plane is hangared, except when you fly, that may prolong the bubbling. The other factor like I said in an earlier post is the age of the plastic. In my expirience the older lexan I tinted seemed to have less problems. and I'm sure that holds true with plex too. Not to say they wont eventually have problems, but maybe the two factors will buy quite a bit of time. I'd be willing to bet that if you tied your plane down outside over a blistering hot florida weekend, You would not be a very happy camper when you returned. I agree now with your suggestion about not being able to see very good in turns through the skylight if using the perfed vinyl. Have'nt flown my KF yet so I hadn't thought of that. Good point. Maybe I'll just call LP and get a one piece "tinted" Canopy
