With what you know, and what you've done, and what you're trying to
accomplish, I suggest you find a source for Waterlox.
www.waterlox.com You'll get the results you seek, without having to
deal with new equipment or techniques.

And it cures more quickly to recoat than WATCO oils, too.

Just that, one thing does the "oak finish" and seal?
