Bullseye vs Star Break vs Combination Break: Which Repairs Hold Up?
Bullseye vs Star Break vs Combination Break: Which Windshield Repairs Last?
Windshield chip repairs can last for years, but the type of break matters. A “bullseye,” a “star break,” and a “combination break” are not just different names; they represent different fracture patterns inside laminated glass, which affects how well resin can fill the damage and how the repair holds up over time. In general, repairs last best when the damage is small, clean, shallow, and addressed quickly—before moisture and dirt contaminate the break. They also last best when the impact is away from the edge and away from high-stress areas that flex with body movement and temperature change. The challenge is that two chips that look similar from the outside can behave very differently on the inside. A bullseye with a clean ring and minimal cracking often repairs neatly. A star break with long “legs” can hide multiple stress points that keep trying to spread. Combination breaks mix both behaviors and can be unpredictable without a close inspection. The goal of repair is structural: restore integrity, reduce spreading risk, and improve appearance. It is not a magic eraser, and the best shops will set that expectation clearly. This guide explains how each break type behaves, when it typically repairs well, and when replacement is the safer long-term decision. If you want the fastest answer for your vehicle, a clear photo and the chip location usually tell most of the story. Bang AutoGlass can review photos quickly and recommend repair or replacement based on real hold-up risk—not guesswork or sales pressure.
Bullseye Breaks: When They Repair Cleanly (and When They Don’t)
Bullseye breaks are the classic circular impact pattern: a small crater at the center with a ring-shaped fracture around it. They often repair cleanly because the damage tends to be relatively contained, and resin can flow into the ring and the center pocket effectively when the break is fresh. In the best-case scenario—small bullseye, not near the edge, not in the driver’s main viewing zone, and not contaminated—you can expect a strong structural result and a good cosmetic improvement. Where bullseyes do not repair well is usually about contamination, depth, or hidden cracking. If the chip has been exposed to rain, washer fluid, or road grime for days, resin may not bond cleanly, leaving air pockets and a weaker-looking repair. Depth matters too. If the impact penetrated deeply toward the inner glass layer, the break may behave more like a split or combination break than a simple bullseye, and the risk of spreading rises. Location is another factor. A bullseye close to the edge sits in a high-stress zone where body flex and temperature changes are amplified; even after repair, edge tension can continue to pull on the fracture. Finally, some bullseyes include micro-cracks radiating outward that are hard to see. Those hairline legs can become the starting point for a long crack later. A professional inspection looks for those subtle legs, checks contamination, and confirms whether the bullseye is truly “contained.” When it is, bullseye repairs are among the most reliable chip repairs you can get.

Bullseyes become poor repair candidates when contaminated by rain or grime, or when depth and hidden micro-legs raise spreading risk.
Edge-adjacent bullseyes sit in high-stress zones where flex and temperature swings keep pulling on the fracture even after repair.
Star Breaks: Leg Spread, Stress Points, and the Real Hold-Up Risk
Star breaks are defined by radiating “legs” or spokes that extend outward from the impact point. These breaks are repairable in many cases, but the hold-up risk is higher than a simple bullseye because each leg is a stress pathway that can extend under vibration, temperature swings, or pressure changes. The longer and more numerous the legs, the harder it can be to fully fill and stabilize the break. Resin needs to reach the ends of the legs to lock the fracture in place; if the leg tips remain unfilled due to contamination or tight crack geometry, the break may continue to creep. Star breaks also form stress points at the leg tips. Those tips are where cracks often “run” when the glass experiences a thermal gradient—like blasting hot defrost on a cold windshield—or a pressure pulse from slamming doors. Another variable is edge proximity. A star break with legs pointing toward an edge is more likely to become an edge-to-edge crack, even after repair, because the glass is under higher tension near the perimeter. Cosmetic outcome varies too. Even when a star repair is structurally solid, you may still see faint leg lines depending on how the fracture refracts light. The right expectation is durability first, appearance second. A professional technician can improve hold-up by using proper vacuum/pressure cycles, controlling moisture, and ensuring resin penetration. Still, some star breaks are simply too complex—especially when legs are long, clustered, or contaminated—to offer the long-term reliability most drivers want. That is when replacement becomes the better investment.
Combination Breaks: Why They’re Unpredictable Without a Pro Inspection
Combination breaks blend features of bullseyes and star breaks—typically a central bullseye ring with radiating legs and additional internal fracturing. They are the most unpredictable category because the visible damage rarely tells the whole story. A combination break can look “small” from the driver’s seat but contain multiple layers of cracking that resist resin flow, especially if there is a deep center impact or if the break has been exposed to water. The inner fracture network may include tight splits that do not accept resin easily, or it may include leg tips that are already starting to run. That unpredictability is why a professional inspection is more than a formality. A trained technician will look for signs that the break has penetrated toward the inner layer, whether the legs have contamination at the tips, and whether the impact crater is large enough to compromise the repair’s cosmetic and structural result. Timing matters significantly with combination breaks: the longer they sit, the more likely water and dirt will enter the complex crack network, reducing repair success. Location matters even more. A combination break near the edge or near a high-stress curvature area of the windshield is more likely to spread, because there are multiple fracture paths for stress to exploit. The right takeaway is simple: combination breaks may still be repairable, but they should not be “assumed” repairable. The correct call depends on depth, contamination, and the internal pattern—things a professional can evaluate quickly in person or often from good photos and context.
Combination breaks blend a central crater with legs and internal cracking, so visible size can underestimate the true fracture network.
Deep centers and moisture exposure reduce resin flow into tight splits and leg tips, which lowers repair reliability and cosmetic improvement.
Because depth, contamination, and edge proximity drive outcomes, combination breaks should be inspected rather than assumed repairable.
Repair vs Replace Factors: Location, Depth, Moisture, and Multiple Impacts
The repair-versus-replace decision is less about the name of the break and more about four practical factors: location, depth, moisture/contamination, and multiple impacts. Location is the biggest driver. Edge damage lives in higher tension and spreads faster; damage in the driver’s primary viewing area may be legally restricted or may create persistent distortion even after repair. Depth matters because windshields are laminated. A break that reaches toward the inner layer, or a crack that shows from the inside, often indicates a deeper fracture that is harder to stabilize with resin. Moisture and contamination are the silent killers of repair quality. Water, dirt, washer fluid, and road grime enter breaks quickly; once trapped, they reduce resin bonding and prevent full penetration, leaving air pockets and a less reliable result. Multiple impacts also change the math. Two chips near each other create a stress corridor that can turn into a long crack, and the windshield may need replacement even if each chip alone is “repairable.” Time and temperature play supporting roles: recent damage in mild conditions repairs best; older damage exposed to storms and temperature swings repairs worst. The honest truth is that most repairs that “don’t hold up” were either poor candidates to begin with or were delayed until contamination made success unlikely. Bang AutoGlass evaluates these factors directly and will recommend replacement when reliability is questionable, because the only thing worse than paying for replacement is paying for a repair first and then replacing anyway.
Fast Quote and Next-Day Booking With Bang AutoGlass (Send Photos)
If you want the fastest, most accurate recommendation, send photos. A clear close-up of the chip, plus a wider photo that shows its location relative to the edges and the driver’s view, usually tells us whether a bullseye, star, or combination break is a strong repair candidate. Bang AutoGlass uses that information to give you a straightforward answer: repair if we can restore structural integrity reliably, replace if the risk of spreading or distortion is too high. We will also ask the practical questions that matter: how long ago it happened, whether the glass has been exposed to rain, and whether the damage is near the edge or the camera area. If repair is appropriate, we aim to schedule quickly—often next day where availability allows—because fresh breaks repair best. If replacement is the safer choice, we confirm your windshield configuration up front so the correct glass is used and, if your vehicle has ADAS, we plan calibration properly rather than treating it as an afterthought. You will receive clear pricing, clear timelines, and clean workmanship standards, with warranty terms that are easy to understand. The goal is not just a quick fix; it is a fix that holds up.
