If I use paint do I need to paint both sides of the plywood to keep it from
warping? I know that if one side of a board is painted and the other left
unfinished that the board will warp.
Thanks for the help.

I used regular Home Depot indoor outdoor on my pontoon boat and it lasted

Thompsons won't buy you much. Use a tough paint, several coats.

I don't think you will get much warping when the plywood is fastened to the
stringers. I heard you were supposed to let the bottom breathe.
I am using MDO plywood (going on 15 years) so YMMV.

Ok, Thanks for your help.

I'd absolutely avoid any rubber backed carpet.

The rubber will rot and be a mess to take care of when it does.

On a pontoon boat I'd use exterior grade plywood, seal it with epoxy on both
sides, screw it down to the stringers and lay the carpet. I might even get a
little fancy and use snaps to install the carpet so I could take it up once in
a while or even after a washdown. I believe you can get epoxy at a BOAT/US or
West Marine store.
