Didn't read all the posts but I would do semi gloss black, or a satin with a clear coat over it. That's how I did mine
the first two coats leave it on the cowl before whipping it off for about 5 minutes. then the next two coats whip on and whip off to get as much of the the back to black residue off. not like there is much but just so it looks clean. best part it didnt attract any dust or crude
best part is i had the bottle for over 3 years and i still have half if it left i only use it on the mirrors and the cowlWill do! I usually leave car projects for the weekend, this one can't wait any longer.
