Cast Iron Welding/Brazing ???
Anyone know the secret to repairing an old cast iron exhaust manifold with a crack? I have tried MIG, Oxy Acetelyne torch, etc with no luck, the stuff just will not stick. Tried it on a later model manifold with no problems. I think it may have been Nodular Iron instead of Grey Cast Iron. Is there a special prep, Acid Etch, Preheat, Welding Rod, etc, that will work? Any help would be appreciated. Cast date on the manifold is late 1968.
