Boat deck rebuild and extension.

[peter]

There were issues with pressure treated wood and the way they treat it. It caused severe reactions with aluminum, which would EAT holes in the boat.

I believe Peter had this problem.

I believe your best best is a non wood solution or wood with lots, and lots of oil based paint or epoxy or something that would really seal it.

Then every screw you put in should also be sealed with something..........

Right. Don't use treated wood. It can distroy your boat. The formula for
The treatment changed in about 2006. Decks are a pain to put in so you only want to do it once.

If I were puting a deck in I would use real marine grade plywood.
Not sure if it can be found locally. There might be some that claim to me marine plywood. Real marine grad has no voids in the wood/layers to trap moisture.

I would call a boat manufacturer like Lund and see if they will tell you the brand and where to get it. I would imagine they would sell it to you.
