Default Re: The Ford Books Fastener Guide

I spray on silicone to protect the S-2 finish fasteners that I use.

Unlike real plating (cadmium, zinc, silver, gold, nickel, etc.), black oxide doesn't add any material, but rather colors the steel and a petroleum solution provides modest corrosion protection. It is a very fast process and fairly large batches are done in about a half hour, at least at my source in Michigan.
