What's the best way to take off the dealerships name plate from the back bumper without messing up the paint ?

 

My previous Z had a metal dealer tag on the rear.

I parked the car in the sun, and along with the heat from being outside, I used a hair dryer, set on high, and focused the heat directly on the emblem.

I slowly pulled the emblem away.

I think if you take your time, and have enough heat, it shouldn't cause any problems

 

If it is stuck on with two sided foam tape, take some strong fishing line and run it along the back side of the emblem like you would if you where flossing your teeth and the emblem will just fall to the ground.
