Danzig -
You may also consider using impregnated paper such as that sometimes used to wrap new handguns in as they leave the factory. This used to be available from SKS Industries: 1-800-365-1117. If they don't have it, I know you can get it from Brownell's Incorporated, in Montezuma, Iowa:
www.brownells.org
The paper is "VCI Impregnated-Non Toxic Corrosion Inhibiting Paper for Protection of Ferrous Metals"
Not certain, but the brand name might be "ANOX-35M"
The package I got had 25 sheets in it, and each sheet was 12 inches long on each side.
I think it is helpful for storage.
