Use gila peel and cling from autozone. $12 a roll.
Anyone who doesn't like it, has never used it.
Just wash it with soap and water, rinse, put more soapy water on one side, then apply to the window and use a credit card to get bubbles out - wet the inside too to make it easier to squeeze bubbles out or you might cause cracks if the window is warm from the sun.
It peels right off if you don't get it right, and you can move it while it's on the window. Cut AFTER you have placed it and squeezed the bubbles out.
Trust me, buy a pack. You won't regret it, and you will never use other window tint again.
I can't find the 5% online, but I called autozone last week and they said they have it and still carry it. I'm sure you can find some locally.
