I'm one of those die hard dedicated SolarFilm users. I thought I would cry when I heard they had closed their doors and by then you couldn't find any in stock anywhere. I still have several rolls but they'll only be used for the most special projects. I won't waste an inch of what I have.
I've tried just about every film covering and for me there is nothing better than SolarFilm. Ultracote has since become it's replacement though it pales in comparison. I have a bunch of Solite (also from Nelson) too but I hate it because the only opaque colors are black and dark blue. The rest are almost transparent. It is light though. The static cling sticking together forever problem is easily addressed by rubbing baby powder into the adhesive side after you finally get the backing off. Just wipe off the excess with a paper towel and apply. The baby powder doesn't affect the adhesion. I've never had the problem with SolarFilm.
The SolarFilm is not ultra lightweight so make sure anything aft of the CG is as light as possible. Also shrink is finite and a bit less then most. Once you reach its max shrink that's all you get. It won't shrink any more so pull it as tight as possible BEFORE starting to shrink and then shrink slowly to avoid wing twist and maybe damage on this tiny bird. I set my 21st Century iron (with sock) to 300 degrees and work fast when tacking it down. Wingtips and curves are easy to do at that temp with NO wrinkles.
Once you get going with this stuff I think you'll love it. If not then I'll take it off your hands.
