Has anyone mixed there own caustic solution for bluing gun parts such as trigger guards, forearms, and etc. I found a recipe online that was a 2:1 ratio of lye to sodium nitrate (or ammonia nitrate) added to 1 gallon of distilled H2O. I was planning on using the sodium nitrate to avoid the ammonia gas. I have bought the chemicals to mix and found it would be a lot cheaper than purchasing premade salts. I was wondering if this would produce a finish similar to what brownells salts would? Thanks, Hereford
