Rain-X Rain Repellent

How does it work?
Rain-X Rain Repellent penetrates and seals the microscopic pores of the glass with a super-slick invisible barrier that helps to repel rain, sleet and snow on contact. The hydrophobic formula works with the natural airflow over the car to disperse rain-drops from the windscreen.  

How long does it last?
Rain-X is unaffected by normal screen washing. Abrasion by wiper blades and trapped grime will gradually reduce performance and durability. Depending on the amount of driving and how often the wiper blades are used, Rain-X can last from 2-3 weeks to several months before a new application is necessary.

When should it be re-applied?
When you notice fall-off in performance. A freshly treated screen will cause aerodynamic run-off of rain at speeds from about 50-60kph (30-35mph) depending on windshield design.

What about previous coatings?
It is not necessary to remove previous coatings of Rain-X Rain Repellent – a fresh application will simply fill in voids and rejuvenate previous treatments.

Can it only be applied to the front windshield?
Rain-X Rain Repellent can be applied to side and rear windows to help improve visibility all the way round.

Can you really drive without using wipers?
We do not recommend driving without wipers, however on a well-maintained screen, aerodynamic forces above 40-60kph (30-35mph) will remove the rain and result in improved visibility. At lower speeds, mainly in urban conditions, and in light drizzle, wiper assistance will be necessary.

Can Rain-X Rain Repellent cause smearing/filming?
No. When correctly applied, Rain-X Rain Repellent improves visibility in wet conditions.

What causes smearing/filming?
Smearing is caused by contaminants being spread across the glass windscreen. Key issues are the cleanliness of both glass and the wiper blade rubbers, and the condition of the wiper mechanism.
