I found a hair dryer, dental floss and stuff called 'Goo Gone' (not to be confused with Goof Off, Goof Off is bad for paint).
Goo Gone is a citrus based product that takes off stickers,gum, tar, ect. and doesn't hurt the paint. Around here (GA), you can find it at most grocery stores with the cleaning stuff.
I've taken off many a dealers free advertising stickers with this stuff alone.
