I've got tint on my rear windshield (99 accord ex) that won't come off without scraping with a razor blade (other methods have failed miserably... Wondering if I can figure out how to take the rear window out so I can at least work on it on a flat surface instead of screwing up my back bending over the back seat!

 

take it to a professional and have them do it. Razor blade will scratch the hell out of the glass
