im not sure if rain x has it in it, but your not supposed to put anything with ammonia on the plastic windows(thats why your not supposed to use windex) as it will take away their luster. i have heared though that your not supposed to drive with the windows iced over(frost probbably isnt a big deal) due to the flapping in the wind, wich can crack the windows, wether thats true or not i dont know. however, when you run the air at full blast with the windows up it blows them out and ive noticed they flap very little if at all, so if the last statement were true, that could take away the chance of cracking the windows
