I went to bare metal on mine just because I need to see what needed to be replaced. I knew it had at least one repaint on it and fiberglass and bondo work on the rockers, doglegs, wheel arches. Glad I did, there were holes covered with fiberglass where my doglegs used to be and holes covered with bondo in the arches. Also, the roof had been peeling with surface rust underneath. It gave me the chance to take care of any little bit of rust I came across. Replaced the holes with solid metal and now I sleep a little better knowing it. I personally think going to bare metal gives it a little cleaner finished look. Maybe it's just me but I think the lines look a little crisper and more defined with the extra paint gone.
