I have been stripping the undercoating from my 66 Nova (6 cyl auto non-SS), and it seems that the wheel wells and floor pans have the original body color from the factory as opposed to black paint. The car is a yellow car. The firewall is also yelllow. I don't remember ever seeing other than black on wheelwells and undercarriages on restored cars before. I am pretty sure the paint under the undercoat is original and would like to keep it original but black is certainly easier to work with. HELP! Also would the gas tank be unpainted shiny metal from factory or did GM put some coating on it for rust, insulation, or whatever?
