Rear can be pulled/sawn off with dental floss, and the remaining adhesive cleaned up with 3M 08987 General Purpose Adhesive Cleaner. (That stuff is stunningly good, given about three minutes of gentle working. Absolutely no trace of goo left behind.)I picked up my black bow ties today. The front one is a simple snap off, snap on replacement process. The rear is attached with double stick tape so that one will take a little more time to swap. I'll do that one tomorrow. I think the front one looks great on a black car and I'm sure the rear one will as well. These should help make my car unique.
