a REAL good clean,sand well with maybe 220 grit...a good primer and some auto paint preferably..regular house type paints won't hold well at all.

I would suggest considering a semi gloss or matte finish. Cleaning a rough surface with flat paint will be difficult. In addition, don't be afraid to break out a spray gun instead of spray bomb. You can doo eet.
