Be careful with Goof Off as it will strip the clear coat pretty easily. Goo Gone will not. I have no experience with Oops. I agree that the hair dryer is the best method. I've used it many times and it works well. WD40 also works well.I assume you mean off the painted surface. Goo Gone/Goof Off/Oops usually works. Just make sure you don't get the kind designed to remove paint. Another trick I've used when removing emblems is a hair dryer set on high. It will make the adhesive soft and you can roll it off.
