sealing plywood
What do you guys recommend for sealing non marine ply? I am going to make a few plywood boards from some 3/8" that isn't marine grade....I don't want to spend a lot on marine ply (at least not yet).
We need a faq for that stuff.

Re: sealing plywood
I used krylon spray on mine ,no clear coat and after 4 sessions I can see the grain of the wood swelling and the nose kick has flatened out a bit.

Re: sealing plywood
It depends on what you mean by sealing. A sealer can just be a thinned down version of the finish paint or varnish that you want to use. I've also used hemp or linseed oil as a primer coat under oil-based varnish. I like the fast-drying Minwax Polyurethane...mainly for the way it sands between coats. I don't bother to thin the first coat with that stuff. A slower drying (and more expensive) spar varnish might be a good choice since your plywood is thin enough to be flexy. A quart goes a long way.
Ecologically the best choice is to use whatever you already have in the garage, or whatever is free or cheap on Craigslist.
I checked the Free section on the Ashville Craigslist, and only found one old ad for a guy giving away four gallons of white exterior paint. Also saw some free plywood in a couple of ads. For a solid timber board, you could snag these headboards for free:

Re: sealing plywood
Quick and dirty for experimental boards-paraffin driven in w/ heat gun or stolen wife's hair dryer. Be sure to get plenty into the edges/end grain parts.

Re: sealing plywood
These days only the very cheapest plywoods are not made with waterproof glue.
Many exterior and all marine plys are water and Boil proof.
The benefits of marine ply are: more layers, thicker face veneers and no voids.
Certain types (okume) are also very light.
If you are seeking longevity, a coat of epoxy (especially on the edges) makes a great primer for most paints.
It also goes on better with a little warmth applied via heat gun or hair dryer after you roll or brush it on.
You have to sand it lightly before you paint BTW.

Re: sealing plywood
I use good old Helsman spar urethane. A couple of coats gives you a really smooth surface.
