Well, I could have just said "spray paint", but that seemed too simple so I decided to have some fun with it.

You could fill entire threads with tips for proper paint technique (and those threads exist on geekhack). If you've never spray painted something before and you aren't quite prepared, then your best luck might be contracting MagicMeatball to do it for you.
I can tell you that the main thing that people don't usually think about is where to do it. It makes a big mess yet requires a relatively clean work environment. I've actually never painted anything that wasn't made out of wood. I had to go online and read up on it. Short answer: come on dude, do your homework.
