Core support "Blackout"
one thing I hate to see is a radiator support painted body color (unless it is black)
It really takes away from the look of the front end seeing the color behind the grill
My cars radiator support is paint the dark blue as the rest of the trim on my car. But he didn't paint the lower part of the radiator surround. I ended up painting it black cause it looked like crap white.
If you are looking for 100 point show it needs to be sloppy correct. If you are making it look good, paint the whole front black so there is no way you see body color behind the grill or below the bumper / front valance
