Fiberglass bumpers on a 68 Barracuda

Any advice on how to make a fiberglass bumper look like stock Chrome? Wrap? Dip? Paint?
I got the bumpers on and mocked up I am now ready to pull off and do the final finish.

I hope to get this car painted and back together for some spring runs.
It is just a hot small block for fun not worried about rules except my own safety.
