1965 Barracuda- Restomod

Ok, so I got my caps polished and cleaned up. A lot of garbage in them, and rat ****.

But now they are good. There is only one issue, each one has some bit of chrome flaking. I want to get them to where they still look good, but not NOS or brand new looking. I was curious if anyone had painted their caps before or if they had any experience painting flaking chrome. I figured on sanding down the problem areas, if not the whole face of the cap, primer, and get chrome in a can.

Ideas?
