This is this is the first time that I have used a metal bluing liquid and it work very well and exactly as described. You do need to follow the surface prep and instructions carefully but that is nothing more than taking the time and patience to do a proper job then the actual process of bluing is very effective and very fast acting. I used it on various small parts of an old machine tool in my workshop that I am restoring and I am very pleased with the result with plenty of fluid left for other jobs.
