Try it without the pad moistening.
Menzerna uses parafin based lubricants in
PO106FF and PO85RD that typically don't play well with most QD's or water. They are very well lubricated products, even though they seem thicker and drier than most others. That's just the nature of the lubes they use. Using a new, dry pad, put a circle of polish on your pad, spread it evenly over the surface to be worked, then work it until the polish goes completely clear and very oily looking. This takes a while with a rotary, and even longer with a PC. I normally work 106 or 85RD for two minutes with a rotary. The time is just a SWAG, though, go by how the polish looks.
Edit: Also note that on the bottle of PO85RD, Menzerna recommends 1500-2000 RPM. I spread at low speed for two to three passes, bump it up to 1500 til it starts to clear out, then do two more at 1k.
