I just redone mine this week and mine had about 4 coats of primer and 4 coats of white paint, all i did was sand it down really good with some 60 grit sand paper till the old primer showed then i cleaned it up and shot some new primer on it and sanded it all down with some 320 grit then 400 grit sandpaper cleaned it all up again and shot the new color on, hope this helps!
