@wonkipop @jeffbowlsby Were these nuts originally yellow zinc or matte nickel? I have two and Theo both the latter though would like to “upgrade” if originality-appropriate.
Thanks!
i think
@914Sixer is right with his comment.
there is a lot of nuts etc on mine that have long lost their zinc chromate coating.
its not just a matter of polishing it off. its a sacrificial coating in terms of corrosion.
naturally disappears rather than corrosion attacking the metal of the nut or bolt itself.
i go with the ageing theory of leaving it all alone rather than renewing it since i am not restoring my car - been going down the preservation road. unless i have to change a part for purposes of maintenance.
