Do you have to tape the trash bag over the window? I need to remove the crappy tint on my Aspire (don't laugh, it gets twice the gas mileage your car does... /ubbthreads/images/graemlins/wink.gif ). It's come partially off, but there's still plenty of purplish residue, and I do have a rear defroster.
Also, can you just use Windex (you know, like that chick's father would, from "Grek Wedding"), since it contains ammonia, or deos it have to be straight ammonia?
