Hey, I picked up a used .22 ruger mark2 from a ingo member.I want to try and reblue it at home. I have never tried this project and am wondering what product to use.And what worked best for you guys ? All I see is BIRCHWOOD-CASEY.Should I use paste or ;iquid , if I go that route.Is there another route I could go ? HYDRO-DIP is a idea I also had, dont know if THAT is a good idea, never done that either.Any other options, I am open to listening.
