The window tint on my Camaro is about as old as the car and purple as Barney. I've gotten it off the side windows, and majority of the back. I'm running into problems on the back window at the top, where all of those non-defroster lines that are less than 1/4 apart are. Everytime I start getting a good pull, it breaks. Anyone got any ideas?

Thanks in advance!

 

WD40 + new razor blade

 

How does WD40 affect the tint, and wouldn't a razor blade tear up those little lines?

 

just make sure the razor is always flat, run with the curves of the window, and obviously dont carve up the defrostor lines, just run into them, and pull it off of them.

The WD40 just helps get rid of all the sticky residue.
