Yeah, I've been told you have to have a nice clean paint job to begin with. SO....like you said, defeats the purpose really. Gotta spend a ton of time and money in paint just to cover it up, which I'm finding out the costs of the wraps, reputable ones, are outrageous! Guess this is more for those guys with money, unlike me, that get bored having a Lamborghini or Bugatti or other, in one color for too long.
