I'm a new gun owner. I plan on getting a safe, but extra money is first going towards more to fill it with. So for temp gun storage that beats the box they came in I pulled this cabinet from a dumpster and spent 20 bucks renovating. I lined the inside with carpeting from another dumpster(I live in a land of plenty), and made a 3 point locking system with some scrap metal.
I have a problem though. On the guns it looks like moisture is coming from inside them and condensing around pin holes and cracks between parts, like between the upper and lower receiver of the ar. I've got a 450 gram desiccant box inside(should be enough, right?), all holes are sealed, and there's rubber around the doorway for a tight seal. The room I keep it in is always climate controlled as well. Any insight here?
