I have tried a lot of crazy stuff on glass, and I must say, for the time it works, RainX is God when it comes to window water beading.

The way I do it is to apply it before washing each time. Then when washing, I can remove any excess left over. It is just part of the weekly routine. It is kind of pricey if you do it every week, but with the amount of money yall spend on the specialty products, it should be in your arsenal.

I use it on every single exterior detail I do, and my customers love it.
