Anyone use an old refrigerator for a dry box to store powder and primers among other things? I have a good old non-working fridge that seals decently on the top freezer half especially. I'd like to make it my dry box---sort of like a dry box for welding rods. Has anyone done this? I'm thinking that the 15w lamp inside would keep things dry enough if it was on all the time. Then I was thinking that maybe the 15w lamp would be too much for the plan. Maybe 4 watt? Anyone who's done this, I appreciate your input. BTW--the fridge is outside but under cover. Thanks.
