Hello badsix,
To answer your question, check out 'kcwoodmfg.com', the second question in FAQ. White Ash. For my question, what is the preferred product for sealing auto body wood frames?
Harry, I have also pondered this as mine is going to be a driver and as much as I can summer and winter sun or rain. I thought about using some Sherwin Williams deck sealer. I've used it on my decks here and it really repels water for years. I also thought about gluing some of the joints, I don't know if this is a good idea or not maybe some one here can advise. anyway I don't think you would want to use certain sealers if you were going to use glue.
