I should add, for Greg and anyone else interested, that I did use a few other different products/coatings in different areas. You may have seen a while back where I used the Eastwood inner frame rust killer. And I used it in many other places than just inner frame areas. I sprayed it everywhere I could get the nozzle tubes in, and reused the nozzle tubes that comes with it with Walmart $.99 spray paint, inside doors and places where the quality of paint doesn't matter, and places that were never painted before from the factory. And I used the VHT "glossatin"black epoxy for finish coats on the entire bottom, engine bay, door jams, everywhere that won't get painted with the exterior. These cars were rusty before they left the factories and dealers, but lasted this long. That's why I say, if we de-rust and recoat all areas they should last another 50 years at least. My 1st 70 RR had a rusty trunk when I got it and was only 6 months old.
