So I had an idea to help the self-polishing of parts during dry fire with rubbing compound.
Found someone online who has been doing it, so maybe not unreasonable of an idea.
Anyone with first hand experience?
This may sound crazy, but one of my favourite ways of polishing internal parts on a revolver is to melt some polishing compound in a spoon and dilute it with a little oil. I then cover all of the internal parts well with this and put the gun back together. Without firing it, I just work the action many times. The more the action is worked the better the polishing job. A quick squirt of spray lubricant helps spread the polishing compound around and makes sure that every moving part is covered. Every point of metal is assured a good polish and there is less of a chance of removing too much metal, as can happen with a power tool. I used this technique on several of my guns including a double action auto and it has never failed. Just be sure not to fire the weapon until it has been thoroughly cleaned. I use hot soapy water first then a bowl of rubbing alcohol, which I dip the parts in. Cotton swabs will help to get into the frame. Double action revolvers really respond well to this treatment.
