Actually there is another way that is a lot safer and will leave a cleaner window. You will need a large garbage bag, windex, and a credit card. It will be best if you can remove your rear deck, and you also want to do this on a warm day, in the middle of the day. Remove the rear deck, and the side pillar panels. Cut the garbage bag so you have a flat sheet. Spray the entire window with windex. Then cover the area with the garbage bag, flattening it from the inside out with the credit card. Let it sit for a while, probably an hour should do it. The just peel the garbage bag off and the tint will come with it.
