Thanks! I am hoping to give a best practices based on experiments for folks who are in smaller or city operations where they cannot sand blast small parts to restore them. I have my doubts about the cold blackening with the oil sealer regarding 10 - 15 years of longevity / protection from corrosion. I have no current clue what could be better at longevity than cold blackening on steel (at home) for replicating the factory blackened appearance. I am looking for alternatives. Any input would be appreciated.
