I'm thinking of painting the lowers on my old '99 Bomber. Right now they're polished aluminum, and I'd like to go either black or white. Any suggestions or links on how to do this myself without making it look like garbage? What should I use to clean it with first? Do I need to use primer? And what type of paint should I use? I've never really done "professional" painting before, I've just used spray paint cans to paint things like seatpost collars and quick-releases.
