Question about one of his favorite finishes... tung, linseed, urethane
mixture... what ratios of these do you experienced people use (of
those of you who are partial to this mixture?) As a newbie, I am
looking for something that has a lot of beauty like tung oil that haas
a protective coating like the urethane. As some previous posters noted
about Norm... I'm not totally digging the thousand coats of urethane.
Not only that, as a newbie, I have found that the oil finishes are more
forgiving of air born dust than a urethane coating...
