Research has proven that glass treatment products can improve your view through your windshield in rainy weather by as much as 34 percent. The improved vision can increase your response rate by up to 25 percent. That could mean the difference between avoiding an accident or being part of one.
Most glass treatments work by coating your windshield with a water-repellent silicone film. The coating makes water bead up and improves the wiper blade's ability to remove the water. The coating also makes it easier to wipe off ice and bugs.
Most conventional silicone treatments last about one month. But a new glass treatment called Aquapel achieves a much longer service life by chemically bonding with the glass. It should last for six months. Aquapel and similar products are available at auto parts stores or online, with larger quantities usually discounted.
Application of Aquapel is simple. Make sure the temperature is at least 50 degrees F. Clean the windshield and allow the glass to dry. Then wipe Aquapel onto the glass and wipe it off. Then wipe on a second coat, wipe it off and you're done.
