wow eh, I guess your keeping it in a place were condensation is avaliable. Iv had a layer of rust not near as sever as that before in my gun closet on my mossberg and ithica. (I hadnt opend my closet in a month, which is very WERID cause Im usually in and out cleaning, admiring, looking what to add etc every other day in my collection). In one of my gun cleaning kits a very soft wool was in it for these purposes. It worked wonders, that and oil and she will be cleaned up.
