ZCORR Vapor Barrier Gun Storage Bags

Tough Laminated Bags Seal Out Moisture, Fight Rust with Corrosion Inhibitors

Eezox rust protectantTo preserve the value of your rifles, pistols, and shotguns, you need to guard against rust and corrosion during long-term storage. To ensure your rifles remain rust-free, we recommend some preventative measures. First clean the bore thoroughly, and remove carbon and gunk from the action areas. Slide a couple oiled patches down the bore and make sure that any bare metal parts (including sights, trigger guard, action, and bolt) are coated with some protective oil. We recommend Eezox, Boeshield T9, or CorrosionX. Eezox leaves a glossy dry film shield with excellent rust resistance. CorrosionX is more like a conventional oil, but with special anti-rust additives. Boeshield T9 leaves a slightly thicker, wax-like coating that blocks all kinds of oxidation, even on aluminum parts.

Zcorr bagsLaminated Long-Term Storage Bags
Before you put your guns away for the winter, you may want to pack them in long-term storage bags. You can get superior protection with ZCORR long-term storage bags. Used by the USMC for arsenal storage, ZCORR bags are like the ultimate zip-lock baggie. They keep air and moisture out, and the interior is impregnated with corrosion inhibitors that block rust. The basic long-gun bags cost $12-$16, and have a velcro closure. The “Collectors Series” storage bags ($22-$30 for long-guns) feature a foil-adhesive closure that is 100% air and water tight. The deluxe preservation-grade ZCORRs, priced at $32-$39, can be vacuum-sealed for maximum protection — just hook up a vacuum cleaner to the special one-way valve.

Our friend Jim Sheppard of the Shooting Wire, has used ZCORR bags for years. He writes: “I’ve used ZCORR bags in the past, but the latest firearms versions are reusable, equally durable (they’re far tougher than a plastic bag) and available in sizes that will protect pistols, carbines and long rifles. Their Collector Series storage bags and Ammunition and Parts Pouches use zip closures to protect a variety of sizes of parts, ammo or whatever.”

Zcorr bagsHow ZCORR Bags Work
The laminated material used in ZCORR bags is puncture-resistant, tear-resistant, and will not harm any non-metal surfaces. Two key elements in bag’s laminate construction allow ZCORRs to block corrosion: 1) the foil barrier layer; and; 2) the VpCI-impreg-nated sealant layer.

The foil layer in ZCORR FSP Bags™ performs two tasks simultaneously; it keeps harmful corrosion causing elements out of the bag and keeps the corrosion inhibiting VpCI chemistry in the bag

The VpCI-impregnated inner layer provides the anti-corrosive properties. The VpCI chemistry impregnated in the interior layer migrates out of the plastic and forms an invisible gas inside of the bag. This gas is made up of VpCI molecules that are attracted to the interior and exterior metal surfaces of your firearm. The gas coats these metal surfaces with a one-molecule-thick layer of VpCI chemistry that stops corrosion before it can begin. This one-molecule-thick layer of VpCI chemistry dissipates off of the firearm when it is removed from the bag.
