Metal finishing question from a non professional


 

I am restoring a 1971 Datsun 240Z and there are a lot of bright yellow nuts, bolts and metal parts that seem to have been anodised. I want to make a very small anodising bath to restore the many pieces back to their original lustre. I can get plenty of info on aluminium anodising but not for steel, although the term I am using (i.e., anodising ) for steel may not be correct.

Steel is not anodizable, Robert. If the parts are steel, the finish you are describing is probably zinc plating with yellow chromate or cadmium plating with yellow chromate. I think you may not want to do chromating at home, involving as it does a regulated carcinogenic chemical (hexavalent chromium) that requires special treatment before disposal. But good luck to you.
