The unpainted parts.

Are you saying the unpainted parts are or aren’t galvanised?

What metal parts of a car aren’t painted? Or more broadly: coated.

The "unpainted" parts are galvanized. Galvanization is essentially zinc paint (with no dye). For the painted parts, the paint serves the same purpose, which is why it's important not to mess it up.

You think hot dip galvanising, zinc electroplating, zinc rich primer, and zinc rich top coats are the same?

Jotun would like a word with you.
