sned it back as well, WC is gonna rip you off for phenolic faced ply....you can get a full 4x8 sheet at whitecap for around the same price...and the sheets I saw in the woodcraft in Tucson, the phenolic was so thin it almost looked like it was painted on. I would get ply locally, paint it and put a coat or 2 of poly on it and you would be just as well off, or better imho.
