Hey all: First time poster, so please go easy on me... Just bought what I think is a restorable '72 240z, and I need some opinions. The car is originally Lime Yellow (112 color code), but overpainted red by someone in the past (now faded.) While inspecting the undercarriage for rust, I noticed the undercoating had been painted the original yellow! I owned a '73 240z about 16 years ago, and I don't remember this characteristic. Is this original or part of a prior repaint? If it is original, should I consider stripping the undercoating to upgrade it? It lacks sig rust (so far) in wheel wells, frame rails and floor pans, but does suffer from it around batt ledge, door jambs, and some spots on body panels. I will post pics as soon as I figure out how... Thanks, X
