does anyone have this on their car? looks like black paint over body color.any reason for it?

coat of a rust inhibitor? Wat does the other side look like?

i post pictures of both sides( the same) if u mean the backside, it's body color. why rust inhibitor in just this area. why not whole area?

Nissan applied this black paint at the factory for appearance reasons. This treatment helped to limit the contrast of bright paint behind areas like the grille. You should also find black paint on the framing right below your seats.

4th photo at the link below has a sentence talking about the black out treatment.

I also think Wick's book talks about it too.
