I'm a strong believer in using RIG.I have never had the slightest rust. When I come in from hunting it gets a good wipe down. I have several sheep skins saturated with RIG. I carry one in a zip lock bag and it's always ready.If you're caught in the rain and it stops. Wipe it down to dry it then go over with the sheep skin.Except for a ding here and a ding there my rifles look like the day I bought them.
