Windshield Repair is not the most complicated thing you can repair on a vehicle, but there is nothing worse than you, or one of your technicians, cracking out a windshield because you don't know how to properly perform a windshield repair.
This rock chip maker can be used on any practice windshield (we recommend Clearshield practice glass) to create chips that you can practice on.
You'd be surprised how hard it is to actually create a chip on a windshield. Windshields are extremely durable. This tool makes it easy (and admittedly kind of fun).
By loosening and tightening the end of the rock chip maker (think eraser end if you think in terms of a pencil), you can increase or decrease the impact. By doing so, you can replicate nearly any type of break. You can make batwings, stars, bullseyes, combinations, and other type of break.
