So i removed my front winglets cause of the damage they had to them, plus i have a hard time getting into the driveway straight. So i got them off and they were being held on with wood type screws. The car was used and the dealer said they had fixed the winglets just before i purchased it. Well long story shot, there is this black rubbery stuff that is left on the bumper and i have tried heat, goo gone and finger nails and its kicking my butt. Any one had this same problem? what did you do?
