Best way to remove stripe?

I always parked the car in the sun depending on which side your doing first. You want the side your doing in the sun, And then I use a heat gun to slowly heat the area your starting to peel off and work your way down the stripe. And then once its off you can use wax and grease remover to take off any residue. You can pick up a heat gun for $10- $15 bucks at harbor freight.
Hope this helps, you should have no problems doing it this way and you won't damage the paint at all.
