If your hull is dull and chalky, I think there's only one single-step way to get the shine back: pay someone else to buff it out! I tried Island Girl, and it works OK, but it's a rather long and tedious process. Buffing our '23' with 3M rubbing compound/polishing compound and then waxing took about 8 hours and the hull looks great(of course my arms damned near fell off!). One thing I found out though: the cheap "buffers" don't work well for compounding. You need a high-speed wheel, lots of compound, and allot of care. Unfortunately, this is a 3-step process!
