A couple of days? I'm a gunsmith school graduate (MCC class of '93). We had a 11 weeks of 'basic' bluing. No handguns or SS/OU guns allowed. Each student was required to blue 5 long guns. You were graded on each one. To get an "A" it had to be flawless, Guild quality acceptable. Out of the 20 students I think 4 received an "incomplete" as they didn't get at least 3 done (3 done, with each being an "A" would get a "C" for the semester). Then, in the second year there was another 11 weeks of "Advanced Bluing", where we were taught slow rust bluing and were allowed to blue handguns/SS/OUs. Again, another 5 guns. There are 'common' bluing shops and top end professional shops. To make real money you have to be at the top end, doing Guild quality work, just like if you're a stock maker or metal smith that does chambering.. (Guild quality work involves a pitless surface when examined with a magnifying glass, no ripples, all corners/edges sharp and the original shape they left the factory, all lettering as it left the factory, and proper, even color with no 'spots'. A "couple of days" would be enough to teach you what you don't know. Top end work, in any field, is where the $$$$ are at. In any gunsmith field today there seems to be two kinds of business,,,,,, those who are doing well for themselves and those that are slowly loosing money. Firearms refinishing is work! I'd be awful hard to keep at it loosing money, breaking even, or only making a little bit of money. A "hard row to hoe"..........
