      You can't predict every failure, but this will fix most major issues enough to get you to a shop or a safe place to work. Give the Jeep a once over, front to back, left to right. Drive it at highway speeds for 30 minutes and source out any shakes, squeaks, rattles, buzzes, etc.
      
      Hope this helps.

What are your thoughts as to how he actuates the sealer?

I've thought about building a diy chamber vac, and would rather just put one of these inside the chamber with this traversing the wall to the outside world. Costs less money and this way you don't need to hook up a separate gauge.
