all that being said, remoil has teflon in it, which helps keep things slideing nice, and wd-40 has alchohol in it, both dry quickley and offer no rust resistent, or verry little. threr are a number of good gun oils out there, I prefer hoppies #9, cheap and does well. just make sure it has no alchohol in it as it can damage your blueing, I learned the hard way.
