Reply to Painting a controller case

So,

I just got a used Oxygen 8. I want to take it apart, and do some fun stuff, a la Ean Golden. Anyways, I know i should give the case a corse sanding, but I don't know what are the optimum paints to use on that sort of surface, and if I should use some sort of sealant afterwards. Anybody got some experiences (good or bad) that they would like to share?
