Kevin, there is a guy up near me that knows how to weld cast iron. His name is Steve Babinsky from Automotive Restorations (
[email protected]) (908) 236-6400. His cars go out to Pebble Beach. You might want to talk to him about the cast iron weld. He told me the cast iron welding rods you buy are from CHINA and are junk. He has his welding rods made here in the USA.
