Dave, we used white lithium grease on the O-rings of our down hole tools when i actually worked and got a pay check. The tools with a double o-ring seal were rated to 20,000 psi if I remember. But the o-rings only made one trip into the well, changed them every run.
Free advice is worth exactly what you payed for it.
