How to improve windscreen wipers?

[Utey]

How can I increase the pressure of the wiper blade against the screen?
The blades lift at speed and generally just smear the screen.
Changed blades, arms, bent arms just can't get them to work well.
Any ideas appreciated.

At 100mph they just flap around in front of the screen. The wee spoilers you used too be able to get don't seem to make much difference. Perhaps someone has been able to source some stronger springs?

One word, Rainex. Once over 80kays you won't need to use the wipers. I found under 80 the wipers are not too bad especially with rainex.
