Best answer is to seal the guns in VCPI bags.
This will totally prevent rust for at least 10 years, and is what the military use to store guns.
You can buy sheets of "Gun Wrap" VCPI paper and special plastic bags or vacuum pack bags with the VCPI already in them from Brownell's.
This will work a LOT better than slathering them with grease or depending on dehumidifier chemicals. Since the gun is sealed in it's own rust preventing environment, each gun has it's own individual protection that won't fail.
NOTE: DO NOT use ordinary plastic bags of any sort. They all pass moisture. The special bags are made of a "hard" plastic that won't pass moisture of allow the VCPI vapor to escape.
