I know that with RainX and RainAway you normally have to reapply every month or two to get the same original results.

The problem I have had with these products is that, although they make the windshield very slippery for water, they make the rubber on the wipers very grippy and the wipers begin to chatter across the windshield. (very annoying!)

Ten months ago I installed the new generation "Reflex" wiper which came with a packet of rain repellent wipes. This wipes performed similar to RainX but without the annoying wiper chatter and only now after ten months have water repellent properties started to wear away.

I am not sure if I should try RainX again and risk wiper chatter or buy a new wiper with their effective wipes...
