Yesterday, my nephew who is a professional gun smith, told me about a method he uses when finishing gun stocks. He wet sands using the oil finish he is using as the lubricant instead of water and he said it fills all the pores to get a nice smooth finish. Anyone familiar or used this approach? I did a quick try of it this morning on the inside if a bowl I was working on which was a bit rough at the end grain and it made it smooth. I was using Tung Oil.
