Heat gun? Hair dryer? I just set my dad's truck out in the sun when it was upwards of 90 degrees, and waited for the metal to get warm. Once the metal is warm, a dab of diesel fuel and a popsticle stick. Came off in under 5 minutes, and I then removed the goo with orange-glo. Worked great, and the paint isn't harmed(you would really notice too, because its black). His 2000 2500 now looks a lot better with zero badges, and those cool factory fender flares. No one be scared of badge removal, its easy(I'm only 15).
