Steve,

Thanks for the reply, clarification, and feedback.

I'm not using wet playback (I generally tend to avoid it), although I know
of quite experienced and successful engineers using it, and have been shown
by at least one of them their method that was water based.

Cutting fluid on a lathe is for lubricant and heat dissipation right?

I just know wet playback that is at least partially water based is in use
or at least has been by a portion of the folks doing transfer work, and I
wanted to breach the topic a bit from this point of view as opposed to the
lubricant point of view (even if both work?). Even possibly hear if the
folks using it might notice a bigger benefit in low humidity conditions
(winter, etc) when applying this technique or notice this characteristic in
the future.

Nathan
