Applied RainX: vision is worse.
Discussion
Hey,
I got so fed up driving in the rain with no rear wiper (3 series saloon), I applied some RainX to the rear and front side windows.
I've been out in the rain today and instead of big droplets there are thousands of tiny droplets creating a "mist". Also, it seems to have impaired the window heater.
Could I have applied it incorrectly? The car had just been washed so the glass was clean and dry. I followed the insructions.

It's behaving exactly as it should. Rain-X is useless on rear screens as it relies on the airflow over the screen to clear the beading. Rear window doesn't get the necessary airflow.TBH I have found Rain-X useful for one thing only and that is to make removal of fly-squash easier during long summer trips in hot weather.
At this time of year it can take longer to 'go off' than in the summer. I've used it on many cars over the last 5+ years and always had good results. Clean dry glass, chuck plenty of the fluid on a microfibre and coat the screen, let it dry, then buff off with another clean, dry microfibre. Repeat for best result. Generally use on the windscreen, side windows and mirrors; rear screen if it has a wiper.
I guess it also might depend on the car but I've always had the water running up the screen; a quick swipe of the wipers gets rid of the droplets for a wonderfully clear view. How people put up with the smeary, hazy mess I see on most cars I just don't know.

Could it be that your car has wax on the glass? I went to take mine to a £10 supermarket wash recently and they must have used some kind of wax once washed. The smearing/beading was so bad I nearly had to stop. When I got back I read on here about scrubbing the screen with neat washing up liquid on a damp pad made out of kitchen towel. You have to put some elbow grease in and scrub the thing for about 10 mins and rinse well afterwards. Also clean your wipers by damping a rag/microfibre cloth with meths and pinching the blade then rubbing along the length. Do this until there is no more dirt appearing on the cloth (you may even have to use several cloths). The difference was night and day with no rain x in sight.
I put too much RainX on my daily driver's windscreen last year, at least I think that's what happened. It left a smear that ruined my vision and the smear wouldn't come off, not even after heavy scrubbing with glass cleaner, car shampoo or washing up liquid. Eventually, after about 4 months of daily driving, being parked outside and weekly cleaning, the smear wore off. Be careful with RainX! 
The main problem with rain x is most don't have the patience to put it on properly In the first place
I have used it for years I can't drive a car in the rain without it tbh its just awful without , you also need to re learn that you don't use your wipers much, re apply to my windscreen every 2 weeks
One day I will give the other products a try but I have been told g tech lasts longer but isn't as effective but I will serve judgment until I try it,

Rain X is not crap.
If applied correctly it works very well. What you do need to do is as others have said is ensure that the glass is totally clean and free from any contaminants in the first place. I either use warm water with vinegar or panel wipe which is a degreaser initially. Then the rain x is applied and hey presto it does what it says on the bottle.
Using plenty of CLEAN cloths is again critical in you getting the best results. I would further suggest that if you can use mechanics disposable latex gloves with your cleaning cloths so as not to rub the oils/sweat etc from your hands onto the cloth and then onto the glass.
Its a question of Results = Effort, that's all. . .

Agreed - an old neighbour had the smearing, didn't have the patience to sort it, so smashed the screen and got a new windscreen
