The Rain‑X® Quantum® Wiper Blade has breakthrough technology that applies water repelling coating as you wipe your windshield and has a unique blade change indicator to remind you when to change your blades.

Water Repellency Technology The Rain‑X® water-repelling coating will also help clear your windshield of harsh winter weather driving elements, such as ice, snow, and sleet. This can help reduce wear and tear on the squeegee and lead to longer blade life.

Rain-X consists mostly of something called Polydimethylsiloxane (PDMS). Try saying that five times fast (ba dum tss). The carbons in PDMS are non-polar, just like the carbons in oil. Water, on the other hand, is polar.

Rain‑X® Glass Water Repellent treats the glass surface with a super-slick, non-stick invisible barrier that repels rain, sleet and snow on contact; dramatically improving all-weather visibility, safety and driving comfort.

Prestone ® De-Icer Winter Windshield Washer Fluid is specially designed to improve winter driving visibility. It is formulated to melt ice & frost fast, down to -34°F. Prestone De-Icer washer fluid works hard to prevent dangerous refreeze.

Designed to deliver proven performance across a variety of applications, these post-treatment water repellents – including silane, siloxane and silicone resins – keep substrates dry while reducing water absorption and thermal conductivity, combating corrosion and increasing the energy efficiency of buildings.

Water-resistant: able to resist the penetration of water to some degree but not entirely. Water-repellent: not easily penetrated by water, especially as a result of being treated for such a purpose with a surface coating. Waterproof: impervious to water.
