I have a 2009 Chevy Traverse. I did something really stupid though. I bought a car magnet and put it on the back of my vehicle. It was on there for about a month and I did not realize that the magnet had a glue film on it. Part of the film pealed off on my car and now it is stuck to the back of it. Is there anything I can use that will remove this from the vehicle? I don't know what kind of glue it is other than just knowing it came from a car magnet put out by a company called, Advanced Graphic, LLC that I bought at Wal-Mart. Any ideas on how to get it off? Thanks!
