Frank, You are welcome. I have learned a lot from his videos. I've done the hot water on a few small parts and been very impressed with results. If it was an old 22 bought at flea market I would say bring it on over. We'll try it. 🤣🤣🤣 A Colt 28 is another matter. In chemistry class years ago we learned even a good stainless will oxidize with electrolyte and dissimilar metals. I have underused electrolysis over the years for restoration of rusted metals. I think it will be acceptable to show inert CW 24 pounder before and after. Not painted after restoration. Just waxed. I will use steam and boiling more in the future.
