Auto shops have a little drill attachment that is kinda like a circular eraser that works wonders... my neighbor works at an autoshop and brought it home for me one day.
we took off an couple inches and it worked great. The prob was that my car is a 91, and it wasn't the paint under the stripe that was faded, it was the rest of the car. It looked like it was perfect factory black underneath. It make the rest of my car (black) look faded, so we just left the rest of the striping alone :/
