Bullseye, star, and combination break are not the same pit
Diameter is the whole break, legs included. The word chip does not pick the kit.
A bullseye is a round cone with a clean center. A star has legs. A combination break has both, and the legs are what run when the car hits a cold morning or a hot highway. Those three shapes use the same resin bridge only while they are still short.
Diameter is measured across the whole break, legs included, and compared with a quarter if the damage sits in the driver's view. A half-inch bullseye off to the side is a routine resin stop. A star whose legs already stretch past an inch is heading toward a replacement even when the center looks like a pinprick.
Combination breaks are the ones that fool a photo. The caller sends the shiny ring. The tech arrives and finds two legs walking toward the frit. If either leg has touched the edge, the resin bridge stays in the van and the windshield comes off the rack.
A previous partial fill changes the shape again. Cloudy resin in the center hides the true diameter. The tech has to see the glass, and the ticket should say the break type so the first trip carries the right materials.
Name the break. Bullseye, star, or combination. The word chip does not tell the van which kit to rack.
