GWBourne - get yourself a heat gun or hairdryer and some fishing line. Heat up the badge and then slide the line behind it, it will come off instantly.
As for the residue that's left behind, it's stronger than your average sticker glue. Get a can of 3m adhesive remover, it's amazing stuff. wd, goo gone, or the likes aren't strong enough. 3m wont hurt your paint, just spray it on , wait a min, and it will wipe off. .
