I would use epoxy to seal it, poly alone is kinda brittle, and tends to crack, breaking the seal....poly and csm mat seals well tho..but depends on the finish you want.

I'd just use a good treated wood for the seats and plan on replacing the wood about the time you redo the seat upholstery. That's pretty much what original would have been in most boats. Should last as long as the upholstery if you don't trap water in the padding.

Check cost of materials to seal the wood vs cost to replace, and then figure that since the seat will flex under load of people you'd probably crack the sealing materal anyway and end up rotting faster from trapping the water in the wood.

What kind of boat? Aluminum/Tin or fiberglass?

I'm guessing the fiberglass boat you're looking for parts and pieces for: boat interior


W/out knowing it's not an aluminum boat, I wouldn't recommend pressure treated plywood. In fact, I'd rather use exterior ply and seal it w/ epoxy over PT either way.

Treated wood can leach copper if wet enough. Ext. grade would do the trick.

Resins work, so does spar varnish,

I doubt it. Softwood plywood, especially fir, checks over time. Even epoxy requires some fabric to prevent this.

The cheapest reliable way I know to seal plywood is to use polyester resin + at least 4oz cloth.

Dimensional lumber or hardwood plywood (like meranti or okume) you could use a thin layer of epoxy.

I believe you're referring to your seat base build. You already have a thread started about it and I'm not sure why you felt it was necessary to start this one. It makes things confusing to the members having multiple threads on the same topic. Other members have addressed this question on your other thread with the appropriate answers IMHO. It's your boat and you can use what ever you want. The tried and true methods have already been stated on your other thread. :confused:
