Your car's windshield is more than just a barrier against wind and debris – it's a crucial safety component designed to protect you in the event of an accident. However, even the tiniest chip can compromise its integrity, potentially leading to significant problems down the road. In this post, we'll explore the fascinating science behind windshield chips, how they form, and why addressing them promptly is essential for your safety and wallet. The Anatomy of a Windshield Before we dive into the mechanics of windshield chips, let's understand what we're dealing with. Modern windshields are marvels of engineering, composed of three layers: Outer layer of glass Plastic interlayer (typically made of polyvinyl butyral or PVB) Inner layer of glass This sandwich-like structure is known as laminated safety glass. It's designed to hold together when shattered, preventing glass shards from flying into the vehicle's interior during an accident. How Windshield Chips Form...

Black spots can show up in a repair for two reasons. The first reason can be contamination. It is important to fix a stone chip or crack as soon as possible from the date of damage. The longer you wait, the more chances you have for dirt and debris to lodge in the cracks. Another cause of black spots is when air gets trapped in the glass during a repair. This can happen when a repair tech does not take his or her time to vacuum all the air out of the break properly. Depending on the amount of time you waited to get your windshield fixed, you can probably guess which of the two reasons caused your black spots. Windshields that are repaired within a few days of damage and have a quality repairman on the job, can have a windshield that is clear. Typically, people would not even know there had been damage.
