Why do you always want to argue with me?
Sometimes you're arguing with me, disputing things I've said, rather than the other way around. It happens all the time when the discussion is about coil springs. (And I'd note that some fairly knowledgeable folks, most of them engineers familiar with the subject, including a metallurgist or two, tend to take my side in those discussions.)
It's your general practice to make claims that aren't supported by facts, evidence, or any other proofs that you're right. You did THAT in this brief exchange. I generally try to offer examples, or otherwise try to back up my statements with evidence or facts. I've also been known to acknowledge my errors when it's shown that I'm wrong. You tend to
argue from authority, which is the same as saying, "I'm an expert and I know what I'm talking about -- trust me."
That said, I believe you are an expert in some areas, but not all; I'd never dispute what you write about knives, knife blades or the springs used in knives. But you're the only one who talks about that topic in this semi-auto forum. You seem to feel your experience with leaf springs is directly applicable to coil springs. You may be right, but that remains to be seen.
Would I want to cold-blue a gun that is in the white? No. (But I have done that.) Would I want to cold-blue a damaged area on an otherwise collectible weapon? (No, but I've done that, too. Part of my reasoning for doing so was that it looked terrible, and were I to have the weapon hot blued, the collector value would be even more degraded.) That Luger was a bring back WWII Luger with matching holster and magazine, take-down tool, etc. The Oxpho-Blue repair on the front strap was indistinguishable from an otherwise original "factory" blue. That was a lucky repair, but lucky things do happen; I wouldn't bet on it happening again with a different weapon.
I'll agree that most cold blue solutions aren't very good, but I don't think they're all the same, that all are primarily copper sulfide (your claim), or that they
all are as bad as you claim. For many folks, cold blue solutions may be the only practical response to a given problem.
