I just bought a new rear spoiler for my 07 GT. It's the GT 500 style. I wanted to be sure I bought one that would cover the holes from the stock spoiler and it will, problem is, it will not cover all the very sticky adhesive that helped hold the old spoiler on. Question is- what is best way to get this off without harming paint? I really don't want to have to get these two little spots repainted!
