There's some special solvent that I always use to get rid of old stickers and stuff, eats away the glue super easy and just peals off. If that shit doesn't work try using a Hair drier to heat it up then scrape it off, GENTLY other wise bye bye paint.
If all else fails and if your paints fairly mint just wet rub that shit off and go get a can of touch up paint mixed up from the paint code in your engine bay VIN plate.
