....especially, if you have a Remington 870 Express! [:'(] I left my beautiful, mint condition, 870 12GA in its case in the closet for about a week or so one time. Out of curiosity, I got it back out and checked it over. It was fine, but was just barely, microscopically, just starting to develop surface rust and tarnish! I immediately wiped it down with a silicone rag and then rubbed it down again with a tiny amount of gun oil.

Never again will I leave my guns in their cases!
