They have an automotive grade adhesive remover by 3M that will take any sticker off.We used to get it by the gallon when removing the decals and stripes off the sides of pickups.I'm sure that it works,100% sure.Get a plastic spreader,like they put bondo on with,or better yet a plastic razor blade and soak with the remover then use the plastic tool and it comes right off,glue and all.A swipe after it is gone and you'll never know that it was there.
