I removed some on a vehicle my son had. The tinting material didn't have the proper decal on it deeming it the correct shade and as my son started trying to take his driving test in it, the person of authority told him he can't take his driving test in it until either the tint was certified or removed. I removed it. The tint came off easy, but I had to wash down the window with lacquer thinner to get the glue off. What a mess!!
