Hood Scoop Paint color - on inside of scoop?

All the bolt on scoops (two scoops, or twin single piece) seem to be flat black - not like they were painted that color, but like the scoop was painted overall with flat black primer and then the outside of the scoops were painted body color (or organisol black for those with that hood treatment). I'm pretty adamant about blacking out stuff behind the grille, so I would vote for something that blacked out what you can see from the outside. I like your idea of just masking off just what is seen from the outside instead of the whole inside of the scoop - I would think that would solve the problem without messing up open hood presentation.
