I'm pulling my 10 year old tint off my car finally because it's purple and bubbled up on the back, and it's coming off anyway. I've already got the sides off and it looks pretty good, I just need to do the 1/4 windows, rear window, and I might have the sunroof done too. My question is that I have no experience with window tint other than pulling my sides off, which turned out pretty good, just time consuming. I'm concerned that I may take out my window defrosters, but I dunno if the extra $$ would be worth having a pro do it. I've read up on it, and I think I can do it, but I was wondering if any of you guys have any input. If I done it myself I was going to soak the window down w/ ammonia, put a bag over it, and let it sit in the sun to sweat the tint loose. But I dunno if I should attempt it or let someone else.
