Ok... one more hour wrapping up tonight after 9:00 and then I'm bluing the etched side regardless of how deep it is. I've lost count of hours now- glad I started this thread.
Oh yeah- Pro Tip: Remove the foil seal on the top of the etching solution after you open it. I just assumed the manufacturer wouldn't use a material that the etching solution would eat through. Bad assumption. Opened the bottle tonight and all the leftover foil was crusty and corroded.
I coat with gun blue and leave it 45 sec or so, rinse with cold water then wipe dry, 3 coats usually with me turns black. Once done i coat in vaseline overnight then wipe dry the next day. I just done my candiru and my 6 but again heres my 3, using the paste.
I usually use several coats of the cold blue too on other things. I want to get this knife out in the sun tomorrow and be sure of what color I've got on it.
I'll probably give it a few more before it's all said and done.
