    Cosmoline is just a brand name for thick petroleum jelly. Basically just a grease. Same as Vaseline. Grease is what is used for long term storage of firearms by the CF. Any grease will do. A sealed plastic bag would be added protection.
    Oil immersion will cause any wooden stocks to rot.

    So if my friend hypothetically wants to put a rifle or pistol in a piece of PVC for the apocalypse or Liberal gun ban, what should he use? Asking for a friend...you might know him; Mike, from Canmore, likes short canoe trips.

    In a perfect world, I'd track down a small bottle of compressed nitrogen and fill an air tight container with it and seal it up. Even better would be a pressurized container. When I did volunteer work with the Toronto Aerospace Museum, we cracked open a nitrogen sealed cell with a hot engine from the 50s. The thing looked like it went in there the day before. I wonder how nitrogen permeable food vacuum bags are.

    Motor oil often comes up as a suggestion of something that is engineered, comes with some certification. Problem is, it is more than oil. It is designed to help with a car's engine issues. It includes a lot of additives, like the polymers needed to get multi-weight. There must be a significant amount of this in conventional oil because years ago some 10W40 was taken off the market due to it not protecting engines operated in heavy loads such as towing. If you want to imagine zooming into the picture at a microscopic level, there are molecules of chemicals in the engine oil that are not from base crude. So you've got acid buffers, polymers, etc. You've also got a certain amount of paraffin included in base crude. Do you think wax is the best choice in protecting that tiny bit of metal it rests next to in the microscopic picture?

    I'd go with the products designed for inhibiting rust. Plastic to keep the oxygen out is perfect. The only problem is, what plastic will not be eaten away by the chemistry of the rust inhibitor? Or is there a rust inhibitor that is not harmful to plastic over the long run? Solvents in a typical gun CLP would likely chew through plastic over time and then the oxygen gets in.

    Plastic pipe capped with a pressure gauge and a nipple. Flex seal over the threaded cap. Swing by the tire shop for a nitrogen fill to 3/4 of the pipes rating. GTG. That green sewer heavy wall is great but pricey if not using scraps.

    If I was going to bury them, that's how I'd go. I have to consider the room I have in the safe though.....my safe space. Get it ?
