Silver solder not drawing in?

FYI Benzomatic solder kit was also a dud

So after last nights failure I came across these items on amazon prime

This one specifically states it is used for soldering stainless and the reviews mention using it to silver solder stainless stills

For solder this is only 3% silver but it is close to the 4% that bobby recommended and it has to be better than oatley of benzomatic. At five dollars it isn't much of a risk.

Those two items worked great. The solder drew in very quickly and I sanded it down and put it to the test with a full volume in the keg and it held.

The stuff I had was Oatey and it sucked. All of it rolled off. Gave up on the day and ordered the harris. Should be here soon and I will give it a shot again saturday. So it sounds like Acid is the key word here.

Yes definitely.. actually this stuff rolled off at first and after a three hour round trip across the border this weekend to pick it up i almost heaved the keg out my window. Then i heated it up again (from below) and dropped the flux on with an eye dropper after it reached its temp... then it sucked it in instantly.
