I feel that I may be the exception because I have always kept my guns in their cases. Living as I do in the "Cheshire Gap" one of the dampest parts of the UK along with parts of Norfolk, very early on I realised that keep everything dry is the best policy. In my early days I had access to VCI anti rust paper by the roll this made things easy just put in a sheet the size of the case lid and things where fine. Then the Government required all guns to be kept in a secure metal cabinet causing a change of plan. Made the cabinet a size to take cases only rather than assembled guns principally to save space. Just in time this product became available and extremely low cost if not free.
Perfect for keeping the inside of the cabinet dry by simply having a one pound bag of the gel inside the cabinet, and just to make sure there is a small sachet of the stuff in every case with a gun.
Just a couple of rules about every tenth time I open the cabinet for a gun I Nuke the cabinet Silica Gel bag in the microwave oven until it releases all its stored water this makes the gel rather hot. After cleaning the gun the case Silica Gel bag like the one in the photograph is given the microwave oven treatment and put in the case with the gun. My gun storage conditions are as dry as a desert and never had any rust on a gun after storage.
