I joined this forum to help you guys who want to remove your badges. To remove a emblem thats held on with 2 sided tape, your best bet is to use a heat gun, and auto body bondo spreader(new).
Use the heat gun to get the emblem real hot, to soften the tape. Use the edge of the applicator to lift the edge of the emblem. If any glue residue is left pick up some 3M adhesive remover.
