Now that I have gotten my powder coating coming along well, I was wondering if anyone knew of a good way to restore original nuts, bolts, clips, etc... Much of my hardware is still in good shape but has some light surface rust and/or lots of grunge. I have heard that most hardware was just black oxide coated. Is this the factory correct finish? And if so, what is the best way to redo original pieces? Any insight would be greatly appreciated.
