Ed, I read your post again and went to the link. The Custom Oil looks like a fine idea. It's nothing new, being just another version of the Oil/mineral spirits/varnish blends. I certainly do approve of Tung Oil, now that I've has some good success with it. As for just an oil finish on a stock, I've got one that I did 20 years ago. Looks great. Lots of ways to do a stock, though I'm not a fan of a layer type finish like spray on varnish, even though that's one of the best of keeping out moisture.
