how can i remove pinstriping (the stick on kind)that has been on my car since shortly after the car was purchased in 1988.these are 9 pinstripes that run along the body moulding down both sides of the car.the stripes are really baked on there from years of sun.i think if i try to pick at them with like a fingernail or something they will pull the paint up with them.they are stuck on that bad.any good ideas will be greatly appreciated because i would really like them off. thankyou.
