If you want a VCI, Zerust VC2-2 is what you are looking for.
I'm with buck91, I may remove moisture with WD40, but for rust prevention I wipe down with FluidFilm on a microfiber rag before storage. I keep the rag in the top and replace it every once in a while.
The rag comes from my window cleaning microfiber stash, when one gets too oily or stained that Atsko Sport Wash doesn't get it cleaned it gets moved to tool duty, and from there to an oil change rag and then to the trash.
