If we're going to have a discussion on finishes, that's one thing. But you asked what options there were for refinishing a stainless gun. As far as carbon steel guns go, there are many more options available, some durable some not. Some beautiful, some not. Some rugged, some not.
What is the problem with naked stainless? Sure, it takes some getting used to but after while it can be an acceptably pleasing look. Some folks actually like the stainless "look" better than blued. I don't, but hey to each his own, I guess.
I believe he was asking what kind of options he had for refinishing his stainless gun, not "please rag on me because I'm new and don't know everything about finishes, yet".
While I'm no expert, I believe you can hard chrome stainless with good results. Give Tripp Research a call. (www.trippresearch.com)
I'm not sure if birdsong's "black T" will adhere to stainless, or what kind of blueing would work on stainless, so I'll leave that to the experts to answer. Perhaps a call to Wilson combat would be able to answer your questions regarding Birdsong's finishes, they seem to have the process down pact.
Another "newbie" question if noone minds. Can you put chrome or other finishes over a parkerized gun, or is it cheaper to trade for a stainless? (If this is a REALLY stupid question please be gentle !!)
You can Black T, ~200, or Titanium Nitride, ~400, coat an SS gun. Both seem like good finishes. Both come in Black. Titanium Nitride is much harder than Black T, but it also requires quite a bit of heat to put it on. Most won't coat aluminum, but I was told that SS would be ok. Those options may seem limited to some, but for a Carbon Steel gun, I would only add Parkerizing to my short list.
I was researching blackening a ss slide release to match parkerized black, and was told that an equal mixture of 1 lb sodium dichromate and 1 lb potassium dichromate heated mixed in 1 gallon water, heated to 300 degrees, would blacken ss.
I'm no chemist, haven't done it, but got the info from a electroplating website.
I ACTUALLY have several stainless pistols Black-Td. While it will adhere, it wears off much quicker than off a carbon steel gun. My goal was maximum corrosion resistance, and I feel I suceeded. However, my guns see hard use, I am not interested in showpieces.
You might consider simply bead blasting the piece. The current Stainless TRPs are finished this way.
