    seems to last forever

    have seen it last 20 years. had a large can of utility unopened for twenty years. used the whole can & no trouble ran great not one leak. have soldered with success joints that were assembled and left untouched for five years . 95-5 , ran like butter.
  • Sorry to disagree bob,

    but I have heard of it.
    Not a problem with me so far,, but I have-had a few fellow plumbers complain.
    I think it may have something to do with temperature changes in the truck.

    In my area,, Kester is still King. ;-)

    shelf life

    i got a jar of handy harmon brazing flux from 1969. can't wait to open it up & test it. i need a brazing project. still got some non- self cleaning sil-foss rod. man, i am getting old . lol
  • sil-foss bob?,

    get in line old friend,, got alot of that too!

    What I AM looking for is some old-time wiping tallow,,, don`t think I`ll ever find that! ;-)

    BTW- How`s P.B. doing?

    After two or 3 years I notice it does start to taste a little funny. I would eat it as soon as possible.
