I have a small aluminum boat that I use to get from my half tide dock to
my mooring. When the summer rains are heavy and a lot of fresh water is
flowing into the harbor (north Atlantic) the slime build up on the
bottom can reach 1-1/2 inches thick.

I'm looking for an anti fouling paint that can be applied to the
aluminum boat that doesn't cost more than the boat. By the time I buy
Interlux' or Pettit's Cleaner, Primer and Paint I'll spend at least 2x
what the boat cost.

Any suggestions would be appreciated.
