I have searched your databases and even some youtube areas, but see much conflicting information. I was going to use a plastic bucket, but found out they are not rodent proof, so I am moving to the coated ammo cans. The primary question is regarding firearm storage. Some say to grease them, others don’t mention anything. Would putting them in a sealed bad work? I would think you might not have the time to clean a greased gun. What about storing any gun oil? I have also heard lighting a tea candle right before sealing it to get rid of any oxygen inside the container is a possibility. – Dan
Yes, use a plastic bag and plenty of oil and grease, especially on the face of the bolt. But be sure to enclose an index note card that says: “WARNING: Grease In Bore and Chamber — Remove Before Firing!!!” A cleaning rod, patches, and oil should accompany each gun stored with this method.
Note that some wooden stocks can be stained or even soften with prolonged exposure to some oils. But fiberglass and other synthetic stocks are generally impervious.
My current favorite lubricant is Frog Lube CLP. It protects metal from rust just about as well as grease.
You can use the CO2 method of displacing oxygen, but do not use oxygen absorber packets. Those are designed for food, not metal! They actually use an oxidation (rust) process that can induce rust on stored metals in the same container.
