Any Walker SST users?

I've been using the Extreme SST with great results for several years. But recently I noticed my SST dried up and became very thick, so according to their website I put a few drops of Canola oil into the vial but somehow I had some doubts of this Canola oil application. A few days later I tried to check its conductivity with a Multimeter set on "Continuity". I made a line with SST on a piece of wood and tried to test it on both ends of the SST line, but no sound from Multimeter, no continuity, no conductivity? Then I dipped the multimeter probes into the SST vial, still nothing. If it's so conductive, as they say, shouldn't it pass the continuity test? I was expecting that it will be more conductive than copper but obviously it looks very resistive. Am I doing something wrong here? Or has the SST lost its onductivity after I applied Canola oil?

Can somebody with a multimeter and SST check this?

Thank You
