I have gone through removing, just make sure that window is insanely hot before you start peeling, took me a little while to figure that out and made a mess in the process, but if it's toasty everything comes off real easy. Use the heat gun on the outside of the window too, use it on the tint and you will make your life more difficult.

As for applying let me know what you find, I am have been searching for the good stuff and it seems ever place that has it wants to install it themselves.
