I drive a 1987 mazda rx7. Great car, love it! Problem is, I started to take off the pinstripe on the pass side of the car (oddly enough, there isnt one on the drivers side, lol) and it leaves behind a residue. I have tried everything from WD40 (works to take off scuffs from cones at autoX), simple green, even...and I hate to admit it...gasoline. Nothing that I can think of will get rid of this old old adhesive. Is there a product, readily available (Autozone, O'Reilys, CarQuest, NAPA, etc) that I can use to remove this old adhesive? Is there some kind of compound? I used a hair dryer to heat the old vinyl while removing the small section I did and that worked well, but the adhesive was left behind.
