DriveSmartBC – Hydrophobic Windshield Treatments

If you are like me, the worst time to be driving is at night in the pouring rain. It’s like driving into a wet sack of coal! When another vehicle approaches, the glare of their headlights can be blinding. Hydrophobic windshield treatments can make it easier for a driver to see well in wet weather.

A study by the University of Michigan Transportation Research Institute concluded that these windshield treatments can result in significantly improved driver visual performance.
In the study researchers found that treated glass increased drivers’ visual acuity by as much as 34 percent and cut response time to a test target from four seconds to three. A single second represents a significant margin of safety, since it translates to about 17 meters at 60 km/h.

There are a number of brands of these coatings on the market with a range of prices. They are applied to clean auto glass and then repel water, causing it to bead and stream off making it easier for wipers to keep the windshield clear and for you to see.

The treatment also helps to repel snow and sleet and make it easier to scrape ice off. Applying it to LED lights can assist in keeping them clean as well.

I have tried two types. The first was a bottle costing between $5 and $10 and the second was a kit for $80. 

A single treatment seemed to last me about a month and there were many re-applications in the bottle. The kit was not as generous.

The only difficulty I found was in cleaning the windshield well before applying it. The kit came with special cleaning materials and instructions for their use. Bottle simply advised to apply to a clean windshield and the manufacturer did not answer my inquiry about proper pre-treatment cleaning.
