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

Your SST is fine as long as you only used a couple of drops of canola oil. For whatever reason, lots of folks have reported that sticking multimeter probes in SST will not show any result. If you have any concerns about this, call Walker Audio at 610-666-6087 and talk to Lloyd.

Trelja is exactly correct. I just talked with Lloyd to confirm: he says, as Trelja points out, the silver is in an organic oil suspension (carrier). The oil is not very conductive and will show no conductivity with a multimeter due to the low voltage being applied. When the SST is applied to a connnection and the connection is then tightened down, the carrier is forced to the outside and the silver remains, creating a highly conductive interface. The carrier dries on the outside of the connection forming a seal that helps prevent the connection from corroding.

By the way, the carrier used is not canola oil but something else. Canola oil is simply the best readily available material for us users.

Hope this explanation helps in confirming and supplementing Trelja's comments.
