Bullseye Chips: The Cleanest Repair There Is

If you have to get a rock chip, this is the one to get. A bullseye is a circular chip with a clear center where the rock struck and a dark ring around it. People usually describe it as looking like a ripple in water or the rings of a target.

Why It Looks Dark

This trips people up, because there is no dirt in there and nothing is stained. The dark ring is air.

A straight on impact drives a small cone of glass out of the outer layer and separates that layer from the plastic layer underneath in a circle around the impact. Where the two are separated, you have a thin pocket of air between them. Air and glass bend light differently, so that pocket reflects instead of transmitting, and your eye reads it as a dark ring.

That is also why the repair works as well as it does. Fill the air pocket with a resin that has similar optical properties to glass, and the ring largely stops being visible.

Why It Is the Best Case for Repair

• The damage is self contained. A circle has a defined boundary, so there is nothing pointed outward waiting to run.
• There are no legs. Nothing to chase resin down, and nothing that concentrates stress at a crack tip the way a star break does.
• The geometry is uniform. Resin flows evenly outward from the center and fills the whole ring at consistent pressure.
• It sits still. Bullseyes are the least likely of the common chip types to spread on their own, which buys you a little more time than a star break does.

How Big Is Too Big

The quarter rule applies here about as reliably as it applies anywhere. Hold a quarter over the chip. If the coin covers the whole thing including the outer ring, you are in good shape.

Beyond that size the outer edge of the ring gets harder to fill completely and the result is less clean, though it may still be worth doing. Location matters too. A bullseye sitting in the driver's direct line of sight is held to a higher standard than one over on the passenger side, because any remaining trace is right where your eye rests.

One Thing That Changes the Outcome

Age. A bullseye repaired the week it happened fills cleaner than one that has been open for three months.

That air pocket is not sealed. Water from rain and car washes gets in, along with road grime and wiper fluid. The vacuum step pulls most of it back out, but heavy contamination limits how clear the final result can be. Nothing dramatic, just the difference between hard to find and findable.

So if you have a fresh bullseye, this is the easy one. Call, describe roughly where it sits and how big it is, and Patrick can usually get out the same day. About thirty minutes, wherever the car is parked, $100 to $125.
