double sided tape like they use from factory. I removed my 4.0 badges using a hairdryer. Just use it till it gets pretty hot(not hot enough to damage the paint tho), and carefully removed badges with a flat screw driver, then just kinda rolled the sticky stuff with my fingers. Bit of a hassle, but no real hard work and no paint damage.
