it's worth it as long as you use a quality product (like 3M). expensive to have a shop do it, and takes a lot of time and patience to do it yourself. not the end of the world though. a good product shouldn't fade. they can scratch or tear if they get abused, but if applied correctly it will take a lot to do that. atleast it's not your paint though.
