No not really . I had a graphics shop do it but watching him I probably could have. The good thing with vynal is if it gets screwed up you can replace it. Mine was garenteed for about 6 yes in full sun.
I didn't get the impression that it was particularly easy. The shop that is finishing my car applied the stripe. The hard part with all of the lines on that car is avoiding bubbles as much as possible. There are a couple of very minor bubble spots if you inspect it closely, but you really have to be looking for them. Otherwise, it looks great. Really sets off the car, particularly with the color of the car and the trunk panel.
