This is strange. We also got the same presentation at the 2014 rally with the CRC lube. At that time, their manual stated to use silicone spray when the jacks are extended for long periods of time. Their current manual still says to use silicone spray for the jacks. Lippert should get all their people on the same page, and if this is really a problem with using silicone spray, they should change the manual. Page #9, note #4
