Though I do not like to use this type of forum for sales, does the Anti-Borax No. 1 Cast Iron Welding Flux look like it will help?

Details can be found at the following location.

I have sucessfully used Anti Borax #2 for brazing cast iron, You ask for the "best", well that I can't tell You, as a can might last You a lifetime, and if it works, You might not ever try anything else. The can I have was My grandfathers, probably purchased in 1970. Anti Borax #4 is supposed to be used for brazing cast iron, and #1 for welding cast iron. I don't have either of these.
