Yes, chrome plastic parts like a car grille are copper/nickel/chrome over plastic.
A truck bumper is copper/nickel/chrome over a steel stamping.
I already explained how stainless was plated.

This likely won't mean much to you, but others may be interested.
Question: A few years back I got some plastic dash board items for a 67 Ford "rechromed" as they were chrome before. The company in Texas that did it (beautiful,by the way) told me they put the plastic in a vacuum chamber and pipe in powered aluminum dust to simulate chrome plating. Was he doing it a different way back then or are they many methods of doing it? I dont see how you can "plate" plastic since it can't attract the metallic particles.
