So you have a rock chip. Don’t feel badly. We all land ’em at one time or another. The question IS, what do you do about it?

First and foremost, you should tend to your rock chip sooner rather than later. By getting it repaired sooner, you lessen the chance of it worsening or becoming a crack and getting moisture and dirt in the chip. Ideally you’d have your rock chip repaired during dry weather and never in the hot sun. If you wash your windshield on a hot day and you have a rock chip, you are at risk of it spreading. By the same token, if the weather is cold and you are running heat in your coach, it could result in a cracked windshield.  At the very least, apply a rock chip patch to keep moisture and dirt out, as this can make an eventual repair less successful.

Not all rock chips are created equal.

Yours may be a bullseye, which has the best repair outcome, or it may be a spider or star, like the one shown below.

The star is more difficult to repair because you have to inject resin into the tiny fractures. Very small chips are more difficult to repair and may have a less satisfactory result. Rock chips near the edge of the windshield are more likely to spread.

As a general rule, rock chips larger than a quarter are not recommended for repair. The larger they are, the more they compromise the windshield. For this reason your insurance company may prefer you replace the shield rather than risk the crack. If your rock chip is in the line of vision (which means within your windshield wiper swipe and above the steering wheel), it is often handled on a case-by-case basis. The concern here is that the repair could cause distortion and again, your insurance company would rather see you replace the shield than risk distorted vision.

The process for your rock chip repair is quick, typically requiring 15-20 minutes per chip. It involves cleaning the site, drilling into the middle of the chip and injecting a resin that will cure, filling the spider cracks to prevent spreading. While repair is typically quite successful, you can expect a better result with the bullseye than the spider. Once your rock chip has been repaired, it cannot be repaired again.
