SB Think that if you go to a scrap metal yard and ask for plumbers lead you should be ok. That is what they call it at the yard I go to in Marshall, Texas. As you are not all that far away would think that they call it the same thing. I use a little paraffin wax as a fluxing agent but there are newer products out there that are probity better. I am Old School and have been doing it the same way for more and 40 years.
