Engine build storage questions

If anyone moves to the shop, it's me! I'm pretty confident I can have a comfy sleep in the back seat of cuda.
With my work schedule, the engine may sit for a week or 2 before I'm able to get at it again. The desiccant bags may be the best bet while keeping bare steel coated and bag it.
Charcoal will absorb moisture better than desican will.
Downfall of using charcoal, you have to put it in something like a soup can.
