I looked at a 67 hardtop today. It had an old paint job on it that was starting to flake. No obvious rust bubbling through and everything looked pretty fair. The owner was very straight forward and lifted the trunk mat to show a 2'x2' area that he repaired with fiberglass mat along with one or two smaller areas. Also on the radiuses part of the driver's floor under the left foot there was more fiberglass patching. Super honest guy and had no problem pointing out flaws. My gut tells.me to walk away from it. I'm not afraid of a project but I'm terrified of what else is hiding under that 20-30 yr old paint and elsewhere. Lots of thick undercoating underneath so hard to tell. When car shopping the old saying is buy something with the body work done and come out ahead. I think I need to keep looking but would love some opinions. If this is the wrong section I apologise Thanks in advance
