There is a product that worwks better than Rain-X. It is made by PPG, the windshield people. It is called AquaPel. The nice part about it is you put it on, wipe it off, and it lasts for 6-12 months. Plus, it is not as hazy when wet as Rain-X.
You can usually find it at Valvoline Oil Change centers, or some car dealers.
It is the greatest reller I have found. I use it on my boat, truck, and R.K.
