Confirming Ranger. No effect on RainSense. Only when it drizzles, or from spray of traffic ahead, especially in the winter with salt on the roads, the wipers cannot clear i all and you would need some aid from the washing fluid.

It's the greatest stuff on earth for plastic boat windshields and roll-up flybridge enclosures.

No, it has no effect on RainSense because it does not affect light transmission through the glass.

How do you get it OFF the windshield ??? Buy a pint of grain alcohol at the liquor store. Carefully wash the windshield with it - several times. Drink the remainder. It's only 190 proof - good night. (Grain alcohol (ethanol) also removes magic marker and Sharpie inks.)
Tip: just apply it on the windshield (leave the traces as is) and just rinse with cold water. No need for buffing at all! Try it
Again confirming Ranger
