Trying to figure out the best way to make this look better or replace completely. Anyone have any suggestions?

 

Tough to tell from the pictures but is that chrome or just metal under the black? Maybe see if you can just get all the black off.

 

Its black over chrome factor deal. Hard to find pcs. Remove sand and paint maybe ...

 

I had this same problem with my Civic. I used this How-To and it looked a million times better

I just painted my XJ and had to deal with this very thing. I scraped off all the loose bits (take it all off if practical), and then ran 500 grit sandpaper across the shiney bits. Then I used this after some etching primer:





It worked great and is a really good match. I put three pretty heavy coats on and it builds up nicely just like the original finish.

 

Those pieces come off quite easily. I painted mine with satin black Krylon fusion. Just because it's what I had at the time and it stuck well. Been on there like 4 or more years. Just cleaned them well first. Just be gentle with them. They're aluminum or something soft and will deform easily probably.
