gmckustom, could you elaborate on why you wash the lead with an acid? Body putty lead is an almagram of lead,antimony,tin, and other metals. They are basically inert as far as having an acid or alkaline PH. The old flux was an acid base to etch the metals and to get a "tooth" for the lead to stick to. I suspect that (the acid flux) is why there is rust under old lead repairs. I am no bodyman, and I am just trying to expand my knowledge. That is why I ask the question. Jimmie.
