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!


Tim,
I like exterior fir plywood. Marine ply is the same wood and glue but more
layers and a solid core. Fir stands up to wet environments, unlike pine and
the glue is waterproof.
Exterior fir was 1/2 the price last time I did bought any. maybe 2 years
ago.
