I kind of agree. Getting the pattern straight could be a bit of a daunting task,,,good point.A friend of mine started doing it on the side. From what he told me, here's what I know: the surace must be in paintable condition- basically, it's paint floating on water. It's difficult to get right. I can only see this being a bigger problem on a fine pattern like carbon fiber.
In my personal opinion, I've never seen fake carbon fiber that was convincing.
Maybe going with the real deal might be the way to go....just a little more involved labor wise.
