Gun cabinet in garage..

in a humid state?

Slight backstory... I want to build my own gun cabinet. The cabinet will not be fireproof, waterproof or air tight, so I would venture to guess a dehumidifier would have to work nonstop in my application if it was in the garage. That being said, here it goes....

Does anyone in a humid area keep a safe in the garage? I'm tossing around the idea as my basement doesnt have much space for what I'm looking for... but I dont want my bangers to rust up and turn worthless either... if they're clean and oiled up is there less of a problem?

I'm open to ideas but I'll be honest, I'm not planning on buying a safe, I'm pretty set on building my own, so that option is out.

Thanks guys
