Catman: I've used paste wax for years to protect my firearms from the elements or as they go into long term storage. Works in the cold and snow, heat and humidity, or rain. You can use Johnson's Paste Wax or you can use any car wax. Sone of the best ones out now are the polymer spray waxes. They go on incredibly easy and give you a hard protective coat. I've had the wax stay on the barrel after lots of shooting and getting the barrel hot, even after the stock starts oozing oils. They work. You may want a softer paste wax for easier application. HTH.
