fvel,
use sperms on your windscreen. It'll work wonders. hehe just kidding. Rain-x is good but it's so darn expensive. The small bottle now is RM20 when last year, it was just RM12+. I already changed to another brand. Just to share my experience, apply rain-x slowly with a polish machine. After applying it, wait for a few minutes and then wipe it away with a clean cloth. The results will be a lot better than applying it with hand. Even at just 60kmh, the tiny little water droplets will slide away. I'm using water repellent with blardy RM20 wipers. hahaha It works good for me so far.
