Have to take the diff out of the cuda soon to do the bushings, just waiting to run the gas out of the tank so I can do it all at once the trunk pan, bushings and get rid of the undercoating. Think I will POR 15 the underside instead of undercoating.
Thats the low milage one? Might want to put on whatever you find to keep it as original as you can. My 67 came with very little undercoating - wheelwells and not many other spots.
I do like epoxy paints for chip resistance. Hammerite is good too, especially over light rust. Vapors are brutal.
