My cars stay parked outside under trees, so there's always dust and gunk on the windshield. I decided to try this P21S washer additive to help boost the strength of my regular washer fluid. I've been using it a few days and like it so far. A single burst of the squirters usually clears up the windshield versus a few bursts before. It does a good job getting tree sap off, whereas the Rain-X bug fluid before would only get like 80% off. Hopefully, this translates to less wear-and-tear on the wipers.
One thing I've noticed is that it thickens up the washer fluid. This causes some deposits of the washer/booster mix to stay on the glass. Not a big deal but just an observation.
