what you do, is take either a hair dryer or heat gun and blow it at the sticker for a few seconds, then slowly pull off the hot parts of the sticker. dont force it off cause it will take paint off. just take it nice and slow. once the sticker it self is off, if there is any glue left on, then take like fast orange or something like that and rub it on the surface and off again (just make sure you apply wax to that area again cause itll come off with the fast orange or what ever)

That should do it for ya if ya have any more questoins on it just ask
