Don't take this the wrong way but bodywork and paint are one of the last steps of restoration. At least that's what I'm told. My current resto is set up as
1) Suspension front and rear and underbody
2) Drive train Motor-Tranny-Rear
Of course there are quite a few steps besided the 5 above (wireharness - subframe - firewall etc etc etc) but everyone I have talked to says do the bodywork and paint last unless the car is really rusted then do the bodywork then the other steps (only if you think the body might get worse) but do the paint last or right before the interior.
