I haven't tried RAIN-X on glasses either... It works great on
cars/trucks/suvs, once you're up to about 30 MPH.
I'd be a little careful with glasses, check with your local vision
store/Dr., about using it on Plastic/Carbonate type lenses; may cause problems.
Just read the CAVEATs on RAIN-X (yellow bottle), "Do not spill or splatter
on painted surfaces or use on plastics unless preapproved by the
manufacturer of the plastic to be treated..." RAIN-X also makes an
"Anit-fog" solution (black bottle), that says "Ends Fogging, Misting &
Steaming on INTERIOR Class, Plastics & Mirrors"; on the back its suggested
uses include Eye Glasses & Goggles, Helmet Visors and Face Shields...
Guess I'll try that next snow storm;;; temps here now have skyrocketed up
to the 40s yesterday, snow and weather have turned "crappy" for XCountry
skiing around here. Tems and weather are to change this weekend, maybe more
I'll post a note when I get to try the "Anti-Fog" RAIN-X....
