I have three rifles that have cheap Chinese bluing on them. I want to strip them down and Parkerize them (they are all steel). Obviously I am going to need some containers to put the solution and parts into. I found some stainless steam trays, but they probably won't hold the parts I want to Parkerize as their standard length is only 20" and I think my parts are longer than that. Those of you who have done this, what is an inexpensive container that I can use for this task? I intend to practice on some of the mags for the rifles first to make sure I do it right before trying this on the rifles.
