I never looked in to bluing, I always seen the perma blue stuff sitting on the shelf at academy so figured it was something you could do at home, then I started reading about it and watching videos...pretty quickly figured out that's not gonna happen. Looks to me like the setup required to do it is highly impractical for anybody who isn't doing several bluing jobs a day. Which makes me wonder how to go about choosing the right smith to do it for you. Do you want the guy that does 1 a month or the 10 a day guy (just randomly pulled those numbers out nowhere, no idea what is realistic)
