Asills,
Is the hull painted presently? If not, is it just dull and lifeless? (sounds like a Pantene commercial) If so, your best bet is to buy a nice ($200) buffer with the right compounds, a few cases of beer and call your buds over for a buffing party. I regret ever painting my boat. For the same time of sanding, prep, taping, priming, painting, running for more paint, more beer . . . OY! If I had just buffed it back to life it would look marvelous now and not NEED a new paint job every few years.
