Beer can collection
My husband has a beer can collection from his teens. Most of it is Tin. We live in Florida. Would like to know the proper way to protect them from rusting. I was thinking mineral oil. I found one site that said Lacquer but said it could mar the paint. Another that said wax them, but that doesn't take care of the insides. And would take forever. They may not be worth anything but he has had them so long they might.. Figured I would come in here and ask the experts. Thoughts?
