I just got mine off a couple hours ago using a hair dryer and a vinyl coated fishing line leader. I simply put some heat on it for about a minute or so, slid the line , ever so gently, behind the upper peak on the pentagon and pulled while applying the heat. Came right off. Just a small residual outline remains. I'll get that off when I wash the car in the morning. Tonight is the bike's night out, SRT can play tomorrow night.
