RE: Rust prevention.
As long as you use a good rust preventative then you should be fine. I use and swear by BreakfreeCLP (Cleaner, Lubricant, Preservative). It is an excellent all around gun care product. It has solvents for cleaning, if lubricates with light all-synthetic oil which evaporates leaving a dry Teflon lube which doesn' t attract dust and dirt, and is a great preservative. I' ve never had any gun rust that has had a light coat of CLP on the metal surfaces, even after handling. CLP was developed for and is use by our armed forces to clean and maintain their service weapons in the harshest envirionments on Earth. In fact, I discovered it while I was a Marine. To give you a clue as to its effectiveness as a rust preventer. The M16A2' s they issue in boot camp are cleaned so frequently and obsessively that on most, including mine, the parkerizing on the barrel from the compensator to the front sight assembly had been worn off to bare metal. But as long as the rifle had a light coat of CLP put on it after was handled it never had a speck of rust.
I trust all of my guns to CLP. It' s just really good stuff.
