[Alberg30] Bottom Paint

[Kevin Blanc]

Let me tell you how we did it. It was the easiest sanding job we ever 
did (and I've done it too many times).

Get a big bucket of water. Buy a drywall sanding pad, the kind that 
attaches to a broom handle or a pole. Buy the pole, too. Buy the 
roughest grit drywall sanding screen they sell. I think it's 60 grit. It 
might be 80.

Wet the pad in the bucket. Sand. Notice how quickly it's coming off, how 
little dust there is, and how clean you sinuses still are, and how much 
control you have over depth of cut. Dip and repeat. If you want to be 
really environmentally conscious, spread some plastic or paper under 
your work. Let the water evaporate off  and toss out the plastic with 
the paint residue on it.

If I hadn't seen a guy at the marina do this just as I was firing up my 
Porter Cable orbital last year, I wouldn't have believed it. I bought 
the drywall sanding stuff and we did the hull, mostly while while 
standing comfortably, in a very easy afternoon. Only the turn of the 
hull is tricky, and even that was pretty easy.
