Stop in for a cup of coffee
I always like to black stuff out that is behind the main sort of focal point / view area. If everything is chrome, i find it to be hard to look at and take in. For instance, I installed a trans cooler last week and since it is behind the grille, i had to paint it black becuase otherwise, all you could look at and see was the ugly trans cooler behind the grille. Now, it looks like nothing is there. in this case, when i look at the grille, i really focus on the up and down bars behind the slats because they are chrome and bigger than the rest of the grille pieces. So by painting everything black and leaving the slats chrome, your eye will be drawn to only the stylistic slats.
