There is a UV-induced polymerization of lacquer process that is used on optical storage device lenses (e.g., CD readers) to improve laser focusing. I have never heard of it used on camera lenses though.
I've had lens anti-reflective coatings redone with materials like magnesium flouride ( I think that what was used) but it's way more expensive than that. Perhaps she was referring to the element cementing material used in many older lenses?
Sherry Krauter certainly knows what she is doing, however. Why not just ask her? I'm sure we'd all like to know more...
