The most common corrosion of ferrous materials is red rust. Red rust is iron+oxygen so it has to be an aerobic process. Remove the oxygen and you remove the raw materials to create rust.

Green rust (like you see often see underwater) is iron plus chlorine

I frequently check on any guns put away for long-term storage, as I don't want to risk having corrosion get started and progress for any length of time.
While I am sure this is a fine product, I don't trust any storage system for longer than a couple of months. The military may be able to afford to absorb the cost of lost equipment in the event of failure, but I cannot.

That rig placed in a PVC pipe, sealed, and buried in the garden will prevent even the zombies from finding it and digging it up!

Now what???

I just went up to the lake house last weekend for the first time in 2 years. Putting it off until it was time to come home, I didn't clean the guns stored there until the last moment, but guess what?

The Crosman airgun (Quest 1000, made in China), anyway, was starting to get a little rust on the outside of the barrel. The Ruger 10/22 stainless, nothing. The Browning B-80 (Beretta) was totally okay, too.

But still. No cleaning or oiling for 2 years -- and condensation-wise the NYS-Canada border is a HARSH environment. So it was all better than expected, but how often can you get lucky?

Now with these mylar ziploc bags we should be able to EXPECT to avoid corrosion? Will the Cosmoline company go out of business? Is this cheating?

is there a dessicator inside the bags?? since i seem to remember corrotion in ferrous materials to be an anaerobe process.. could be a clue to throw one extra inside the bags just in case...

Also, if any one is interested in purchasing ZCORR Bags make sure to use the discount code "fieldandstream" at the check out page to save 10% on your order. All domestic orders over $50 ship free.

Could the air tight/vacuum plastic(garment)bags they advertise on TV serve the same purpose? Of course you would need to eliminate any light to penatrate the plastic, right?

My first grandchild is due in December. Now I know how his first gun will be stored until he is old enough to use it.

Dave,
The Aussies perfected gun storage back when the Govt. decreed destruction of most - all guns.
Now there are 'tube guns.'
I will not go on into any detail from there.
If you know any Aussies, they may make a remark.......
onward,

Ralph the Rifleman,
The problem with garment bags is that over time contaminants such as oxygen and moisture can permeate through the material so to safely store your firearms you would need to apply extra oil or grease. The extra oil or grease also means you have to clean the firearm in order to use it. Either one of our ZCORR lines (vacuum or original Velcro) only require a normal cleaning which means firearms are ready to be used right out of the bag.

I am thinking of buying a few of these for my father in law's birthday, we went into the gun closet the other day and started pulling out guns that he didnt even know he had, several are very old and already showing signs of corrosion, and they would definitely be the kinds of things I would like to save for future generations. Cool product, will definitely look into buying a few.

Depending on the size of the firearms, yes more than one can be put in a single bag.

ZCORR,
I should have asked. Do your bags enclose entire rifles stock and all or just the barreled action?
