So today at the job site for the first time I saw sealed unfinshed wood. The whole board is compleatly sealed (top, back, tounge, groove), Company or Mill is called Ten Oaks, in Stuart VA. Goes together really nice. Only problem which is a minor one is some boards have a build up of sealer on the tounge and groove making your butt joints open a little bit. Out of 30 bundles I think I scraped maybe 4 boards to get them a bit tighter.
