I Tested Bluing, Parkerizing, Cerakote & Nitride Outside — A Clear Winner!

📖 Get The Old Gun Hand, fifty years at the gunsmith's bench, written down: https://ivansjournal.com Go and pick up the gun that rides in your truck or your holster. Look at the edges. The muzzle, the slide corners, the bolt handle, the spot where your hand always lands. If there is a finish on that gun, that is where it is losing. Not in the middle of the receiver where the brochure photo was taken. One of these four finishes has been run past two thousand hours in a salt fog chamber. Another one showed rust before the first day was over. On paper that should settle it. It doesn't, and the company that posted the big number says so itself, in one sentence most people never read. So nobody writes in about it, here is where I stand. I've owned guns in all four. Old blued rifles that came down through the family. A Parkerized surplus rifle that looked like it had been through a war. A Cerakoted bolt gun I bought because the marketing promised it would shrug off weather. And nitrided pistols that get sweated on, rained on, dropped in gravel and wiped off with whatever shirt is closest. For years I believed newer meant better. Then I stopped asking whether each one fails and started watching how. The Parkerized rifle humbled me the most. A flat gray, crude-looking process from the First World War era, and some of those service rifles are eighty years old and still wearing the finish they left the factory with. The technology mattered. The habit mattered more. What we go through: Why bluing is not paint, it is a controlled black rust, and why the oil is doing most of the work Hot bluing, rust bluing and cold bluing, and which one is only a touch-up product Why you should not refinish an honest old blued gun just because somebody said bluing is obsolete Parkerizing, the porous crystal surface that was built to hold oil, and why "porous" is the design, not the flaw Zinc against manganese phosphate, and the greenish tint collectors chase on old Garands Cerakote's two thousand and three thousand hour salt spray numbers, and the one sentence on their own site that tells you how to read them Why a coating fails at its edges, and guns have a lot of edges Why Cerakote is only as good as the shop that sprayed it Nitride, Tenifer, Melonite, QPQ, and what a molten salt bath actually does to the steel Glock's finishes over the years, and what is verified against what is forum lore The one word to ask about before you buy anything advertised as nitrided Why the best answer is often one finish layered over another The verdict, in order, for a gun that lives outside Said plainly on the shop work: hot bluing, Parkerizing and nitriding all involve caustic solutions or molten salt at high heat. None of them are a weekend garage project. If a gun needs refinishing, a qualified gunsmith or professional finisher is the right call, and the question to ask is not just what color but what is underneath. There is no trick in any of this. A bigger lab number does not promise more years in the field, and none of these finishes is rustproof. It is only that nobody prints "keep it oiled" on the box, because nobody makes a living saying it. I wrote a book about exactly that kind of lesson, the habits and mistakes years around guns taught me. You will find it at ivansjournal.com. Tonight, wipe down the gun you handled last, put a light coat of oil on it, and get it out of the damp case. Then go look at the edges on your carry gun and tell me honestly what you see. Tell me in the comments what finish has held up best on a gun you actually used hard, and what climate you live in. Gulf Coast and high desert are going to give very different answers, and both are right. And if Cerakote has chipped on you, or held for years without a mark, say where it happened and what kind of use the gun saw. #GunFinishes #Bluing #Parkerizing #Cerakote #Nitride #Melonite #Tenifer #QPQ #GunMaintenance #RustPrevention #Gunsmithing #CarryGun #HuntingRifle #Glock
