Re: Paint Remover for anti-fouling paint
The drywall sanding technique is intriguing and would like try it sometime. But when we stripped our boat's bottom 4 years ago, I used a 3/4" wood chisel and the paint just peeled off. No dust and not that much elbow pressure needed. Two of us did all 38' in a 10 hour day. I sande the bottom with a a shop-n-vac hooked to a 6" random orbit sander using 80 grit followed by 120 grit disks. That took 6 hours down to the gel coat all around. All together it was 26 man hours; not bad given the scope of the job and 20 layers of paint.
I would not try to sand the whole thing off and would NOT use anything except a random orbit sander in any phase. Strippers are expensive and take a lot of time to work. I saw a guy work for days getting paint off and it probably cost a fortune. But others on SailNet have done it so I'll defer to their opinion.
