I think we are getting spoiled by the super finishes on some of the newer guns (Glock Tennifer, etc.) Blued guns rust, that is why the military went to that ugly Parkerizing. My older blued guns all rusted and needed periodical refinishing. That is why I carry Stainless Steel mostly these days. My .22 rifles are all meticulously cleaned and then waxed after every trip out of the gun safe as are my shotguns. IMHO, blued guns look better, but they will always require TLC to keep the rust monster at bay! I find that for a carry gun, waxing works better for the finish than oil. I use good old Johnsons Paste Wax or Simonize (yellow can for either.)
