I took an old upright freezer last fall to put in my garage to keep my paint, glue and thinners in. I put a small 15 watt light in it to prevent it from freezing as I had no heat in the garage at that time. It keep the temp around 50-60 f when the garage would get down to 10-15 f . My problem is that all of the metal containers form heavy rust on the cans. I am not sure why or how to prevent it. I am hoping to use the freezer during the summer as it get over 100f here for several days in row during the summer. Any suggestion on how to prevent rust?

Switch to plastic jars. They work great.

A freezer will keep moderate the temperature (which is good) but also keeps the air from circulating, which probably encouraged the formation of condensation and then rust.

I wonder if you could put a small computer fan in the back or bottom to ventilate it? Might have to switch to a higher wattage bulb to compensate for the heat loss.

Google ‘dessicants’ – you can get the tub of stuff that absorbs water (then you dump it out and replenish) or you can get a large pack of the type they stick in shoes. People use them in gun safes to prevent rusting.

I am trying the computer fan as “joein10asee” suggested. Drilled a 3/8 hole to let out some of the air in the box out. Placed in in the airway just past the fan so there would be pressure to force some of the air out. There is a 3/8 hole in the bottom which was for a drain to let some fresh air in. Will see if this works.
Thanks for the suggestions.
