yes...cold wont help. When it warms up use your goo gone and your fingernail....
it will scrape off but may take some work. lol

I used my hair dryer to keep the car and the adhesive as warm as I dared, alternating between applying heat and the Goo Gone-soaked rag. Keeping the adhesive warm makes it a lot easier to remove. The other trick is to try to "roll" the adhesive off the car body.
