I removed my pinstripes and door molding with a heat gun, a hair dryer will work tho, They do make a less expensive rubber eraser wheel for the end of a drill if you choose to go that route? After removal I would clay bar the area and put a few coats of wax on it.
Depending on age of how long the stripe has been on it, mine being 11 years old when removed you can still see the halo in the sunlight, even after a high speed buffer has gone over it with a cutting compound, Its not bad but i know its there, I will attempt to wet sand and buff it in the future
