I'm going to use the WSJ lubricant on the side and intermediate housings after I lap them, just because it is simple and convenient to do.  I make no representation of what the long term efficacy will be.  It is a complete experiment that will take years to show any results (and how would I test it without a control anyway), but it is only about $25.  I'll also see if I can coat the oil, corner, side and apex seals, but I don't hold much hope for that to be effective at all.
