Does anyone know if you can put RainX on your sunnies, ie Ugly fish, WileyX ?

I have not put it on my lens's but do use is on my open fase screen, full face screen, Spyder and car windscreens, works great on each of them.

IMHO

Thanks all, I'll give it a try.

 I read on a bottle that  I had (awhile ago) that it is not recommended for plastics.
