i just bought a car and the back window is blurry from bad tint... it seems that the rear defrost doesn't work anyway, so can i just take a razor blade to the whole back window so i can see?

you said that the defrosters dont work? if so, go out and buy some tint-off, i used axius and that worked great, if the lines dont work, then yes you could just scrape everything off.

Yeah, tint-offs are great!
