you know when window tint starts to get old and turn purple? well i decided to take on the challenge of removing it myself tonight...again. it took me 2 hours to get 2 windows done a couple weeks ago with a razor blade and "goof-off" adhesive remover. tonight, i remembered that i had a heat gun!!! thought it might speed up the process. can you guess which one i used the heat gun on? instead of 1 hour per window, it took 5-10 minutes. wish i thought of it two weeks ago.
