Thanks for the detailed info. I've used Oxpho Blue before with very good results. I've always struggled to get it even with the cotton ball method and had never thought of dipping the parts. I've also skimped on the prep in that I clean with a good gun cleaner, then scrub with Simple Green and finish with a hot water wash. I need to up my game a bit and stop being lazy with the prep. Your results show that it's worth the effort.
I had done touch up to other guns before and gotten spotty results....even if they were consistently spotty; so I thought I'd better figure out how to do it right for this pair. With the proper prep that result was achieved with one application. Now if I could just figure out how to get my 1895 Mauser in the oven...or had a large enough plastic tank...and a lot of oxpho blue...
