It hurt to type that thread title.
Does anybody have info on the materials used in pickup covers, both the base material and the electroplated metals for finishes. I suspect that nickel is used instead of chrome on the "chrome" covers, while of course gold is just gold (probably 14k or so?)
I have methods by which I can find out if nobody knows.
I'm sure the chrome and gold are just plating. Most are probably nickel.
