Anyone who was taught to use linseed oil, either boiled or raw, had a fool for a teacher. Years ago I read a number of articles on finishes wanting the best for both looks and protection. I ran across, and still have an article that was put out by Fine Woodworking Magazine that was a study on the affects of different finishes and the transfer of moisture on wood products. The very best was a coat of paraffine that completely sealed the wood and allowed no transfer of moisture what-so-ever so was rated at 100. The absolute worst was Linseed oil that actually attracted moisture and was rated at -3.0. All the other types of finishes were somewhere in between with all of the oil finishes near the very bottom of the list as far as moisture protection.
As usual, the Brits are a century behind in technology.
