Hello Hans -

The monowiper, IMO, has a bit more of a difficult time keeping up because of the big area that it needs to cover, and the design of the spring mechanism that makes it "swoosh across the windshield. I do two things to help the monowiper and to improve driving visibility:

1. I bought a bottle of Rain-X and applied a double coat to the windshield.

2. I use Rain-X windshield washer fluid to keep the application "fresh" on the windshield.

Water just beads right off, and when I'm cruising at highway speeds, I seldom even have to turn the monowiper on. You'll still need it at speeds below 40MPH, but you'll notice a drastic improvement in visibility.

Be sure to buy several gallons though, because if your washer tank is like the one in my C230, you can fit about 50 gallons of that stuff in in the tank!
