I believe it's the turret on the LAV III, and the ramp on the Bison. However, I'm not a driver of those, so I can't be 100%. The fluid itself is a very high temperature hydraulic fluid. Also, part of the problem is that we are bound by standing offers, therefore MUST go through Sentinel, and they acquire it from France. The "grade" of this fluid has very specific properties for military use, thus, not just any will do, and that is where the added time comes from. To add insult to injury on this topic, I had a sea can FULL of the stuff last September, but it all had to go to HAZMAT disposal, as it was recently expired, and the mechanics would have refused to put it in the LAVs. Fun world I live in eh?
