What is a Bullseye Chip and How to Repair It

What is a Bullseye Chip?

A bullseye chip is one of the most common forms of windshield damage. It occurs when a small, hard object—like a rock thrown from a truck tire—strikes your windshield. This impact creates a small cone-shaped crater on the outer layer of the glass, often with a central impact point surrounded by a circular ring that resembles a target or a bullseye. While it might look like a minor cosmetic issue, it is a structural compromise in your glass.

Why You Should Repair It Promptly

Ignoring a bullseye chip is risky. Because your windshield provides structural integrity to your vehicle and acts as a backstop for your airbags, any weakness can cause the glass to fail during a collision. Furthermore, the combination of Washington’s fluctuating temperatures and road vibrations can easily cause a simple bullseye to bloom into a long, spider-web crack. Once the damage reaches the edge of the glass, repair is usually no longer possible, and you will need a full windshield replacement.

How Our Mobile Service Works

At Auto Glass Guys, we bring the repair shop to you. Whether you are at your office in downtown Seattle or your home in Olympia, our technicians provide a seamless service:

1. Assessment: We inspect the chip to ensure it hasn't reached a size or location that requires full replacement.
2. Preparation: We clean the site, removing glass shards and moisture from the impact point.
3. Resin Injection: A professional-grade resin is injected into the damage under vacuum pressure, filling the air pocket and bonding the layers of glass back together.
4. Curing: We use a UV light source to harden the resin, restoring the structural strength and clarity of the windshield.

Does This Require ADAS Recalibration?

Many modern vehicles feature Advanced Driver Assistance Systems (ADAS) with cameras mounted behind the windshield. A small bullseye chip repair typically does not require ADAS recalibration, as the repair process does not involve removing or replacing the glass. However, if the impact has caused a crack that sits directly in the path of your lane-keep assist or collision warning sensors, we will always discuss the safest path forward with you.

Frequently Asked Questions

Q: How long does a repair take? Most chip repairs are completed in about 30 to 45 minutes, allowing you to get back to your day quickly.

Q: Will the chip disappear completely? The resin restores the strength and clarity, but some minor scarring or tiny remnants of the impact point may still be visible depending on the severity of the initial strike.

Q: Does it matter how old the chip is? It is best to repair chips as soon as they happen. If debris or rain gets into the crack over time, it becomes harder to achieve a clear, professional repair.
