At my place of work, we are building a 36' x 36' timber framed pavilion out of local white pine. My history with timber frames is of unfinished wood, both in my own house and for a pavilion that was done for the local Rotary Club a few years back. However, we want to put a clear, penetrating finish on this frame, and I have no idea what to use. I'm avoiding the big-box-store stuff such as Thompson's Water Seal; I don't think it has any value. The very-high-end stuff, such as Land Ark or Sikkens, is hard to get. I'm looking for suggestions or recommendations as to what I can use for a finish that will penetrate the timbers, not look like or act like a film finish, and has some preservative qualities.
