i've got an older rossi 5 shot 38 that had been cold blued 3-4 years ago,then had been poorly stored and rusted.in the process of cleaning the rust most of the cold blue came off.leaving no blue in some places and some of the original factory bluing in others.i was thinking of browning it just to have something different.how would i do this?do i strip off every bit of the bluing,before browning? any advice is appreciated.thanks
