I was wondering abotu using salt-treated plywood on the Marquis deck.
I'm not a feared of paying for marine grade, but Jimmy the carpenter
told me that the newer salt treated woods are about as worthy as
marine grade at a fraction of the cost. So, what's the opinion?

I'm even wondering abotu using hybrid decking like you'd use on a
porch. synthetic mylar etc mixed with wood. The stuff is weather
resistant as all get out!

Does the composite stuff come in sheets, or were you going to use boards,
like

I'm thinking of resurfacing my deck with that stuff. Expensive stuff
though.

The beach house we have access to in Hilton Head has that on the
walkway to the dunes and on the deck that sits on the dunes at the
beach. It's at least 15 years old, and still looks great.

Only problem is that they have sagged in places between the joists
holding them up, worse than a wooden board would have in the same
situation. They seem to need a little more support? Might be worth
talking to a local professional about that.

Needs double the support. And depending on the batch, there are failures
also. My buddy got replacement for his Trex last year. I am in the process
for a new deck from Trex myself. They had a bad plasticizer for a few
years. Unfortunately they replace the deck material but not the labor or
the $330 were of deck screws required.
