After reading the 3M adhesive catalog I decided to go with super 77 initially and make sure I like the way the car looks. The products that have higher temp ranges are pretty much going to permanently bond the plastic and fabric so if you use one of them you better be sure this is what you want. I have the new Crystalline tint on all windows including the windshield so my car temps are greatly reduced but I will likely exceed the 120 degrees on occasion so we shall see. Worst case scenario is that I will have to do the project twice. I have plenty os fabric and the techniques are similar to covering a model airplane which I have done for two decades so that will be fine.
I will do an update as I gain more experience with this project in this climate. Can't wait for the fabric to arrive so I can get to it.
