Goo Gone or 3M Adhesive remover, that shit is just gonna take time to get off. If you can find one a 3M Stripe Off Wheel also works great. http://www.amazon.com/3M-Stripe-Wheel-07498-Hardware/dp/B00063VT0G
We don't really have anything in the Adam's line that is aggressive enough to get that off.
3M Adhesive remover works great!
Soak it good and let it sit for 5 or 10 minutes!
