I personally don't do wraps. I've yet to see a single one done to the point of "Wow, looks like paint!". There's always a join, or a leading edge, or a bit missed like under the bonnet or the engine bay.
Colour should be the least important bit of a car. And yes, I'm aware of the irony of me saying that after all my anti-Resale Grey/Silver posts on here. True, though.
