I can understand a hundred ways in which a copper-nickel-chrome plated plastic emblem can fail to meet expectations. But I can't understand how something that contains nothing ferrous can possibly generate red rust. Somebody help me too!

I found this reply in another question(44207).
"Some shops are now using a nickel/steel mixture to help abate the cost of nickel."
This might be the reason why the parts get red rust.
