Storing Your Gun

I was visiting with a local gunsmith friend this morning and the subject of cleaning/storing guns came up. He stated that he never oils the outside of his guns. This came as a surprise but he went on to tell me that oil floats on top of water. If moisture gets under the oil or was there when the oil was applied it will be trapped there and can cause rusting and pitting. He said the best thing to do is to wipe down the exterior of your gun with a silicone impregnated cloth. Water always beads up on silicone just like a car wax. He said he also uses carnuba wax on some of his guns.
