Advice needed on how to clean/polish old ugly chrome bumpers

I used foil and coke to get rid of some light rust pitting on a barracuda bumper and it did a decent job. To make it shine I buff it out the same way I'd buff paint with a couple different compounds starting with aggressive and ending with something that polishes it out nicely. You can only make an old bumper look so good. Then at that point you have to decide if you can live with it or if you need to get it rechromed or buy a new one.
