Last stylus preservative...anyone still use it?

I bought a bottle of Stylast, Last Stylus Treatment, System Formula 5 a couple (?) years back and haven't used one drop after I read this thread:

Don't think I'll ever use it.  Don't know why I keep it.

  I was thinking about putting lube on the stylus, then thought that it's a minute layer between the groove and the stylus, and wondered if it takes a minute amount of signal away.  Kind of like putting a thin piece of plastic wrap around a microphone, as an extreme analogy.
