Do it! It's the best free mod there is! Well, not on my first car-my 99 Deep Nazy Blue Zetec had racing stipes on the front doors and the WD-40 f'ed up the paint on all four doors. My T-red 00 SE, however, I took a lot more time and left no marks at all! My friend couldn't find where they once were until I told him they come straight off the fender emblems!
