The copper holds well on the silver paint, but nether the nickel nor the chrome 
will. The copper plating is to thin to help protect from the heat.
Then the nickel makes an exellent bond with the copper, while the chrome will 
peel from it.
Then the chrome will perfectly fuse onto the nickel. Also, the nickel makes an 
harder, more resilient, substrate.
You go from "soft" (the plastic) to prety hard (nickel then chrome).
