I did not have good results with Rain X. Perhaps I didn't apply it correctly or perhaps my windows weren't completely clean, but the Rain X seemed to cloud the windows and I had a very difficult time removing it.
My experience was the same. Hate the stuff. The only way I got rid of it was to replace the windows. That was not the only reason the windows were replaced but it sure helped with the decision.
My experience showed if it was NOT ABSOLUTELY FRESH it was worse than not having it.
The fact that the raindrops, light rain/spray, rolled off easily did not make up for the mess it made when not FRESH or the wipers had to be used as they eventually did in heavy spray.
I is h++l to remove resisting alcohol, lacquer thinner, acetone, xylene, and various other chemicals. No way will I ever use it again.
