Frequently Asked Questions
What are the dots on a windshield?
The dots on a windshield are called “windshield rain repellent dots” or “micro-dots.” They are tiny dots of a special coating that helps to improve visibility during rainy or snowy conditions. The dots are usually made of a hydrophobic (water-repelling) material that causes water to bead up and roll off the windshield, reducing the amount of water that enters the driver’s line of sight. This improves visibility and reduces the risk of accidents caused by water-related visibility issues.
How do windshield rain repellent dots work?
The micro-dots on a windshield work by creating a surface tension that causes water to form beads and roll off the windshield. This is achieved through the use of a special coating that is applied to the windshield in a pattern of tiny dots.
