The Caig fader lube might be OK for VCA faders but I do NOT recommend it for Ultimation, later 9K faders at all, or any other moving fader. It seems to leave a layer too thick for proper conduction, no matter how thin you try to lay it, and you get dancing faders.
I stick with the P&G oil only for bars and tracks on all P&G faders. Small faders also.
Fader Lube is also brilliant for carbon faders and pots, but don't go spraying the 100% solution into things. It should only be applied in a controlled way onto tracks. The F5 is Ok for a little blind spray.

PS: A studio owner had me look at his stereo receiver because the volume pot was scratchy even after spraying Cramolin Red into it. Yeah, it was a long time ago! I opened it up and he had sprayed so much over years that there was red Cramolin butter all dried and collected between the front and sub panels. Nothing ever got to the pot. . .
