How sure are we about this, or rather how temporary is not permanent?
  After the horrors of WD 40 and "center pin lubricants" being truly
temporary, I have only recently begun to use Protek (CLP) on centers.
 Also because "watering" (alcohol & water) has yet to fail. But I
tried Protek on tight jack flanges in a friends Kimball console,
(1977?) and soon will return to check them.  

So I am wondering if anyone else uses Protek on centers, and how do
you like or dislike it?  Does it last longer than say two years?
