1968 Gauge dash housing restoration question

[1968GT500CS]

Hello,
What is the best way to restore the black camera case and Crome dash housing?  Is there a Crome paint that anyone has had good success with?  Or replacement is the only way to go?
See pictures...
Thanks for any recommendations.

I've had my original instrument dash pieces restored there.  Excellent communication and workmanship.
