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.

Maybe some teflon (tm) powder added to some enamel paint???? A
$40 experiment...

Paul's outfit also sells coated copper powder at $15/ lb.
He may not have mentioned it from fears of electrolytic corrosion.
It's fair to say however, that copper is THE marine growth inihibitor
- maybe it's outlawed because it can be toxic to useful marine life
too???

Copper is a no no on an aluminum bottom. Electrolosys will eat the
bottom away. I tried some on an aluminum lower unit of an outboard
once and it almost destroyed the outboard.
