Matte black caliper paint as hood paint?
I used 4 cans of OER Organisol on my gts. It laid down quite well at 3.5 cans. I used the last 1/2 can to get some sag/runs/etc to match the rest of the car. The hood started in gel coat (and jb weld) when I started.
I would do the bumper black and hood in Organisol. It's looks pretty cool in the sun.
