058, that is interesting, but I do not know too much about the plating process, and what can be done to restore integrity after the fact. I do know the process upsets temper on heat treated pieces. I'm not sure of the differences in adverse effect from nickel, decorative chrome, and hard chrome. I do know that most chrome shops (hard or decorative) cannot keep up with demand as they are so heavily regulated by EPA and others. I think this plays favorably into the hands of powdercoaters, and folks who have other wear resistant solutions other than the hard chrome. Good Luck Detroit Jim with your race project.
