Use a hair dryer / heat gun to carefully warm up the area and peal it off. Use 3M adhesive remover to get the remaining glue off. It will not damage the paint. Available at any automotive paint store.
Thanks Larry!

I like to use a hairdyer over a heat gun. Heat guns get too hot IMHO. If you are careful they are fine, but too much chance for error working on a painted surface. My wife does not mind if I use her hair dryer..... if she doesn't find out.
Mineral spirits will usually take off a lot of the adhesive as well and shouldn't harm paint. DO NOT use acetone.
