I think he is wanting to paint matt black on the hood...........
Mike, I might would paint the whole truck green (or what color you may be using), mask for the black on the hood, then spray DupliColor sandable black primer on the hood...... You can polish the whole truck then, and that will take care of the edge where the primer was sprayed, and give the primer a little sheen.....
Just make sure you can spray the primer over the clear you use on the body..........
