The Sailkote Idea is very intriguing for several reasons.
First, its dry-so its doesn't pick up dirt, debris, and likely has less odor
second, it permanently bonds to the applied surface, making it very durable to repeated use and seemingly (to my feeble mind) not more toxic than the permanent lacquers on wood or finishes on carbon. They actually claim that "it will not transfer" from the original surface to another.
third (possibly most importantly) its hydrophobic (sorry mo. huntin), so blood and other wet slimy stuff that it comes in contact to is actually repelled, making the slick lubricating value that much more effective. A blood suffuse environment wouldn't even slow it down in theory!
Fourth, its simple to apply, no bake-on rubbing or buffing. just spray evenly and let dry (which happens 'quickly').
finally, on the website, they make the claim , "Sailkote is typically five times as effective, and lasts much longer than, wax, oil or Teflon® based lubricants."
I see no reason not to give her a go.
