Applied RainX: vision is worse.

[switch007]

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.
