Hello all. I wasn't sure where to post this, but this was my best guess. I have a 87 Corvette on which the previous owner installed window tint on the back hatch window. The tint is starting to show it age. I tried the black plastic bag trick with ammonia, but the tint delaminated and the base layer is extremely difficult to get off. Unfortunately the car has window defrost so I can't use a razor blade. Anyone have any ideas? I've heard steam will remove the tint and adhesive.
