I used Nova on my plastic parts which comes wiht 3 different polishes. Based on the starting condition, you work up to the finest, which is almost like water.

As for the chrome, if it's not too bad, I'd leave it alone...maybe touch it up with a chrome or pewter paint stick. If it's bad, then you might need to redo it. There's a guy in Columbus who did a nice job on the chrome on my dash housing and instrument lenses. He was sick, but I recently heard he was back to doing them.
