My recomendation is to get a small angle grinder and use a scuff pad attachment and feather those areas that are chipped and smooth out the rest, then use Duplicolor Bumper Black Paint. Remember, that is sitting above your rear window, and I would be inclined to think that if you paintedd it shiny, it would allow a reflection back into the window. I sprayed mine the Bumper Black and and bunch of other things also, love that stuff.
