I prefer semi gloss, that is what I spray on the various car trim pieces...

Best to wet sand with 600 grit paper, get some prepsol or alcohol and wipe it off afterward. A tack cloth (basically a sticky cloth that removes dust without leaving marks) is a good thing to do before you paint. Try to paint out of the wind, and out of direct sunlight.

Good idea to clean the whole thing off first with some powdered ajax or comet cleaner and a red scotchbrite pad. That will clean the grease off, so you do not sand it into the PC with the 600 grit.

Excellent recomendations +1 on everything mentioned by Mr. Linc.

Paper towel and cloth Rag lint will show up big time on flat black becuase it dries so fast it'll have slight texture. The semi-gloss will lay down flatter and will allowing cleaning.
If you use a spray bomb purchase a well know brand for maximum durability and spray the first 2 coats on lightly untill coverage in maintained then next 1-2 coats a lil' heavier.

This might be a little over the top ?;
A catalyst activated automotive paint (In ureathane or acrylic enamel) will yield the best looking and longest lasting finished product for sure. It'll be basically Gloss Black with a "Flatning agent" added. You can get a Qt of paint made,hardner,reducer for about 30-40 bucks(maybe cheaper) if you get a economical brand such Omni,Kirker at the automotive paint supply store.
FYI, you'll need a compressor and spray gun also.
