I ran into a long term, now EX, Nikon rep, works for another brand now.He said that Canon and Nikon techs use filed down chopsticks, and a solution of 70/80 % acetone (aids fast drying) and 30/20% denatured alcohol.On the other hand, over time does the lubricant reach a nominal state?The D3S has a bit of this, and I'm used to spot checking or shooting an NDF.Haven't read the entire thread here BTW.My $.02 cents.Rob
