I would agree with the last contributer. Our Spirit 36 was not painted except below the waterline, and looked like a silver bullet. One option we considered was printed vinyl wrapping similar to the all over advertisments you see on taxis and buses. However the operators funds did not stretch this far - but it would have been interresting to see how well this could have worked. I have also heard talk of a self healing coating from New Zealand that you can paint on aluminium which keeps it shiny and new looking - but don't have more detail.
