I recently had my bumper re-chromed on an old car. While changing battery cables I made a rookie mistake and drug the positive cable across the new chrome. It made a nice 4" long arc mark across the chrome. The cable traded some copper to the chrome and pitted it quite deep. I sanded the deposits off and can see that the chrome seems to be gone down to the nickel and some copper is also showing.

Is this repairable?
Can I polish this area and expect it to look descent and not rust?
What are my options?

Please help.

Chris.
