Peter's No.2 Blue flux has been recommended in the newsgroup for bronze welding steel. Peter's Black has been recommened for brazing cast iron. Where do you get it? Google hasn't been much help. Amazon and eBay don't list Peter's brand fluxes although they have some other brands. Where on line can I buy Peter's fluxes, or other brands of flux that are proven to work well for brazing steel and cast iron.
