    Cutting oils

    The clear is best for wife it is like a after shave . The dark does cut A36 and pipe better but your wife will not like the smell. She will have you stay far far away. It one part most never talked about is smell. Even try pouringa bottle perfume in dark did not help my wife. Dave
