Hi mft,
I believe it depends a bit just what year car the dust shields were on… generally they were a dull cadmium or zinc plating. I believe it's possible some shields had a gold dichromate wash in addition to the plating.
Regards,
Alan

Alan is correct...again! They are stamped steel plates that are zinc plated (for corrosion resistance); and some were given a (yellow) dichromate wash for that gold color (even more protection from corrosion).
I think the best way to go is to wire brush those parts or blast them to get clean, then shoot a couple of coats of VHT aluminum colored Hi-temp paint and bake them in an oven per the can instructions. It creates a good, solid ceramic painted surface that will last for MANY years without any corrosion. That's the same thing I do to alternator housings, so that they will not get oxidation on the surface.

I buy the rotor shields with the correct plating, and then I go to Eastwood and buy spray paint that is supposed to duplicate the plating color. I'm not NCRS so I have shields with the correct plating and also a paint protective cover that approximates the plating color.

ALL of the shields are plated with zinc. Those that got a dichromate dip, turn that gold color....for a couple of years, anyway. After a year or two, the gold ones turn back to a dull oxidized zinc gray, just like the ones that did not get the dichromate dip.

If money is no object, the best thing to do with them is have them powder coated with 'chrome' paint. BTW, 'chrome' powder coat paint isn't as shiny as chrome; it looks more like zinc plated steel. Hmmmm...
And powder coating is TOUGH!!!! Blast them and powder coat them, if you want them to last [almost] forever. Baked-on Seymore Hi-Temp "Cast Blast" is a more economical alternative.
