I've used Watco Danish Oil finish over the years as the only finish on cherry and other woods in the belief that it not only gives you the natural oil-finished appearance, but also hardens the wood. My perception is that it actually does harden the wood, but I've never tried to scientifically test that. I notice from a lot of posts that most Creekers seem to use BLO. The Watco is very expensive, I assume much more so than the BLO. Other than cost, what are other pros/cons of BLO versus Watco?
