Hey now, I just finished reading an article in Fine Woodworking- June '09 regarding exterior oil finishes. The product that held up best was from a company called Smith & Co. http://www.smithandcompany.org/. It is called [Epifanes Clear Varnish] and in the test that were ran it outlasted the other products big time, Watco, McCloskeys and water based clears. To be fair, I did notice it took 5 coats of Smiths vs. 2 and 3 of competitors and it is pricey at around $78. for a kit that completely covers 10 sq. ft., but for a small furniture gig this would be the way to go.
