I peel lots of vinyl at my job, and a heat gun will work fine. Yes, it does get hot in a hurry, but if it's hot enough to where you can't touch it, then the stripe will come right off. Just don't hit a spot for more than a few seconds from an inch away or anything like that, and you'll be fine. Like someone else said, if any adhesive is left, use some goo gone, but if you have any, mineral spirits work the best. But with it being a pin stripe, you should just be able to take some alcohol and a rag to it and be done with it.
