Using info givin' to me by a friend(in the custom painting biz) who does flawless work, your wait I'm sure, depends upon the paint you use. Sanding, use 320 to even out any runs or irregulaties, sand complete body with 1500 and then step up to 6000(it's called jewelers cloth) and sand again. I'm not sure about what pads he uses. I notice that his paint jobs have incredible depth and not a wave in site.
