96% tin - 4% silver solder is made by several suppliers. Harris Allstate,
and Brownells are some of them.. It melts at 475° F.

Small areas can be physically cleaned and repaired with a soldering
iron, with all trace of lead removed of course. Finding a source of tin
is the problem here. Regular acid flux [ZnCl] works fine.
