I would think the best way to do it would be to tape off the rest of the hood, about even with the scoop....and then scuff as far as you can reach under the scoop, and then paint under the scoop. Then you could feather the edge where you painted, rescuff the black and then shoot the rest of the hood. The sure enough painters that read what I just wrote are probably and think I'm ! It just looks hard to make that area of the hood look good if you don't do that kind of work everyday.
