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!

I looked at everything when I decked my pontoon boat 20 years ago. We
had a Wolman plant here at the time and they offered to pressure treat
any plywood I would bring them but the guy who ran the plant said PT
really only protects it from bugs. If water is your issue, save your
money. I ended up with MDO plywood (one side) and it is still going
strong after 20 years in salt water. That is basically 7 layer
exterior grade plywood with one MDF layer. You would probably have the
same luck with BC
The main thing is to be sure everything is sealed before you put it in
and seal all penetrations. The only bad spot I have found in my
current rehab is from an unsealed penetration.
Cut all of your pieces to size, paint them on all 6 sides with 2
coats then install them. Paint it again to cover the screws. Bristol
Palin will be running for president before that plywood goes bad.

Yeah, but will it last for her eight years in office?
