I religiously apply RAIN-X to all my windshields and have been doing so for years.
With a good coat of RAIN-X, just about any old wiper-blade works wonderfully.
Once the road-speed gets up past forty, I can turn the wipers off.
Yesterday, I even managed to bend/kink the right-side blade/arm such that it finally gets down in that dip that is in my windshield, instead of bridging across and leaving it un-wiped; we'll see how long that works.(the last glass that got put in has a swag in it that shouldn't be there)
I have been contemplating rigging up one of those water-tanks and pumps that use garden-hose, like the off-roaders have been doing to spray the mud off the glass, and keep the tank filled with de-icer, for those times when nothing seems to keep the wipers clear; maybe put a heating element in the tank.
