I just checked out Brownells and here is the name of the produce Ray is talking about:

KICK-EEZ SLICK-EEZ

Mfr: KICK-EEZ

Makes Recoil Pads Slick & Grab-Free

One application makes your rubber recoil pad "super-slick" for faster gun mounting; completely eliminates clothing "hang-up". Goes on easily; dries to a friction-free, clear film that won't peel or crack. Can be used on any rubber recoil pad (except Terminator brand).

SPECS: Kit includes Cleaner, 2 fl. oz. (59mL), Pad Treatment, 1 fl. oz. (29mL) and instructions.

$23.95

I may get some for myself.
