Was under the car this weekend to fix a small radiator leak, thought it was leaking through the threads on the drain plug... when I was chasing the threads with a pipe tap, I noticed that the solder joint for the bung was loose.

What do I use to re-solder the bung into the tank? I have already heated up the area and pulled it out; will scrape off all the paint and clean up the area.

Didn't know if I should use silver solder, what kind of flux - if any, epoxy, etc.

Thanks,
