I had a magnet from my son's school on my car. I placed it on the gas tank door, not the body. I tried to take it off when I washed it to clean underneath and I couldnt get it all off! The magnet ripped and parts of the magnetic backing is stuck to the door! It is like cement. I tried glu gone and it would not get it off. I took a butter knife and chipped some of it off but i dont want to chip the paint. I have NEVER heard of this happening to a car magnet before. I have a suspicion that a student at a rival high school thought it would be funny to super glue the letter. I may have to replace the gas tank door. have you ever heard of magnets melting to a car??? or do you think it was super glued??
