Blas is right. Invinca Shield is kaput. The good news is there are plenty of shops that can install this film--3M or other supplier's--clear shield. Chet is right, too. If you've never installed the stuff, it's best to pay the price for a pro to do it. That's what I did with my Cobra after I messed up a piece.
After Invinca Shield shut their doors, I bought the material locally--it wasn't 3M's--and installed it on my GT40 and Mustang. I did this because I'm Scottish and I took notes when the technician did the installation on my Cobra. The secrets are a good pattern to start with, clean hands, an Xacto knife, scissors, lots of water in an spray bottle with a drop of detergent in it and LOTS of patience. Little imperfections will go away with time, so you have to exhibit some restraint and not overwork the film.
By the way, the Mustang and GT40 turned out as nice as the Cobra. And, no, I don't want to go into the installation business.
