Ya know, alot of old schoolers hate spray paint and swear by the brush. I think it comes out looking crappy when you use a brush. You can definately see brush marks. Like in a house, if you look hard enough you see the cut lines.
Ya gotta use a high quality natural bristle... And cut the paint with a thinning agent. A brush can do an immaculate paint job with proper prep and whatnot!
Foam -rollers- work great, even with oil-based enamel... Again, thin the paint and it'll eliminate air bubbles.
Me personally, I'd only use the foam -brushes- for wood stain.
Other than that, sand it down. Grit graduation pays off if your wanting an immaculate finish. If you go to 100% bare metal, even better. If you go to bare metal in some areas (to eliminate rust spots, etc) MAKE SURE you feather in all in.
Then, degrease. Twice.
Acetone works great if you move quick. MEK buys you a bit of time.
Then, hit it with a tack cloth if you feel the need, as it eliminates any dust particles that touched down.
Now prime it with a COMPATIBLE primer.
Then lay down your color. Patience is a virtue between coats... And a heatlamp or direct sunlight is a definite plus.
Finally, post pictures!
I am envious that you can get away with black... Down my way we have a lot of caliche dust, and it shows like chalk- therefore I go with the stereotypical red cab/black drawer toolbox paint jobs, or industrial grey for lockers/cabinets.
