    me that means teflon powder on felt, McLube on metal (and polished  
    metal without corrosion or burrs). 

  Since we're dwelling in minutia, I recall a conversation I had some years ago with a tech person at McLube, who said that adherence of the product to the applied surface was enhanced if surface was NOT highly polished.  DISCLAIMER: It may have been the only 1708 (grey) Mclube that he was referencing,  At one point I was more familiar with the composition of each than I am able to recall now.  Clearly, we're talking subtle here, without burrs and crud. 

  In any case, I need to go back a few weeks and look at the explanation of how VS works.  If you assume that, with either the whippen cushions OR the let-off button punchings, the dimpling is simply compression, then, if VS restores the fiber dimension and density of surrounding material, it would seem to have legitimately accomplished its goal. Then again, if there is, in fact, fibre destruction, it would seem that some aspect of the affected area would have to be  different from the surrounding material.  

  I wouldn't have even gotten involved in this, but for my momentary misperception that Chris S was talking to me:


    you don't need to sand, retaining all material and removing the indentation
    with the liquid swell is sufficient and allows the material to last longer.
