Of course I would love to use epoxy and an epifanes finish, but let's face it, $$$$$. I'm not afraid of having to sand a re-coat every few years if I have to, but with care on making sure everything is sealed, will the Cabots do the job for protecting the wood/leaks?
I plan on my exterior walls being plywood sealed (encapsulated) with exterior paint or something similiar, even henrys asphalt emulsion if it doesn't dry smelly!

And over top of the plywood, my siding being sheathing rated pine beadboard. Something similar to this: http://www.homedepot.com/h_d1/N-5yc1v/R-202089045/h_d2/ProductDisplay?langId=-1&storeId=10051&catalogId=10053
Which is what the Varnish would be for.

Thanks to you all ahead of time for your help!
BTW, anybody used these guys? Closest non-box store near me.
