After hunt care goes a long way to prevent rust. I have hunted salt marshes in the rain and your gun will literally turn brownish red with a light rust by days end. If you don't address it, it will turn into damaging deep rust in short order. Like the next day. I break the gun down into it's basic components. Wash the barrel(s) in warm tap water and dry. Wash all exposed metal that came in contact with the salt spray with a warm water soaked rag. Dry the metal with warm air after you wipe the water off helps. Then coat with oil. Removing the stock from the metal isn't always necesary but is good insurance against rust in the inletting and can be done later because you are usually to tired to mess with it that night. This has helped to keep my guns rustless.
