70 Corvette dust shield plating

[Lynn]

Here are pics of the RF dust shield.
Sadly, the LF is not usable. But, I have a spare. Just haven't tried cleaning it up yet.
I may be searching for a survivor LF.
Glad to have two pristine rears.

Frankly, I cannot tell just by looking whether these are cad plated or galvanized. I am certain they are not hot dipped galvanized. That process leaves a very distinct pattern. Just LOOKING at them without any kind of chemical analysis, they COULD be electroplated galvanized. Hard to tell on a 54 year old part!!!

Roy S told me:
"Front: dull cadmium without dichromate conversion coating. These tend to get chalky look to them with aging.
Rear: punched from galvanized metal sheet, sheared edges are bare steel from the shearing action which could and did rust."

I let this one soak in solvent (Crown PSC1000) for about a week; then scrubbed on it with a soft scotch pad. As you can see, there is still some discoloration on it. I didn't want to scrub hard enough, even with a fairly mile abrasive, to disturb the original finish.
