Aahh, the hood vents, yeah those are very easy....clean with dish soap and scrub brush, dry thoroughly, spray everything with satin black or flat black, and either: wipe tops of fins while paint is still tacky with rag dampened with lacquer thinner - or - after paint dries, scrub the the fin tops with #0000 steel wool.
If you go the thinner/rag route, make sure the rag is not "loosely" rubbed across the fins as this will cause the rag to go between the fins. You want the rag to be tight around your fingers and just rub the tops of the fins and be sure to turn the rag often to keep using a "clean" section of the rag. After paint completely dries, you can follow up with #0000 steel wool to polish any residue from the fin tops.
Either method works well. I personally like the steel wool method on dry paint as the thinner method requires wrapping the damp rag around my fingers and I really don't care to have the thinner soaking in my skin.
