OK all I have a problem that I'm sure many of you will have come across.......
One of my gun cabinets is fixed inside a cupboard that is on an external wall in the house (old house no cavity etc) I am having trouble with my guns getting rust on them even though they are oiled. This is no doubt down to condensation because of the outside wall etc. Have tried the silica gel pouches and the napier pouches but I would like to find a better solution as I'm constantly having to replace them. Did read somewhere about puting a 12v battery and a bulb in there but I guess I would be forever changing the battery so the other option would be a 240v bulb and a plug but not keen on drilling holes in the cabinet.
Any ideas to solve the problem would be much appreciated
