All pins have a light coating of oxidation on the surfaces that, unless removed and polished with Flitz, will abrade the felt and cause premature wear. I have tried McLube and followed up behind someone who used that black stoff on pins and felts and I had major problems recleaning the pins. I will have to replace them as soon as I can get the time. The Flitz prevents oxidation reocurring for many years and by using a light film coating of the teflon type lubrication the wear factor between the two is reduced by a factor of five. Try this combination on you next severe wear location and observe the wear time. Have a nice weekend. Newton nhunt@rci.rutgers.edu
