My 306 has a matte black bonnet
But that's only because the previous sprayed it after it flew up and hit the windscreen. He got a replacement bonnet which was red, not blue like the car.
And I can't be bothered to spray it blue.
I wouldn't go spraying bonnets black, unless the car was black :rasp:
All my own opinion of course, it's your car Ezra, do with it as you please.
