This windshield long crack repair kit is an upgrade kit for auto glass repair business wanting to add long crack repair to their business.

The Long-Crack Crack Master Wonder Bar Tool is designed to not flex the glass. Flexing down on the glass when doing a long crack will push the crack closed causing an under-fill and spots. That is why this tool has a single custom-made suction cup at a proper distance from the injector that slides. The leveling nuts allow for automatic leveling. Just push the cup down, level the injector and you are ready to go. The center pressure bolt allows for extra pressure when needed. 

The crack-opener tool is the secret to easy and fast long crack repair. Here again it must be of proper size to allow for leverage and mechanical advantage without causing the crack to spread. Our crack-opener symmetrically opens the crack to create an overfill. You will see resin come out of the top (surface) of the crack when you release it. That is what you want, for a complete fill you must overfill.

The two wonder bars can be assembled into the Crack Master Bridge for stone-chip repairs. 

Adding long crack repair to your windshield repair business puts you in the repair vs. replacement market. You can put an ad on the internet, in the Yellow-Pages or Google AdWords and see a profit, which you cannot do just repairing stone-breaks/chips.

This upgrade kit gives you the famous 26-year-old Multi-Viscosity long crack repair method. Adding crack repair to your existing auto glass service can save consumers hundreds of dollars.

This upgrade Kit of Wonder Bars includes a 2-inch stiff suction cup. Switch the suction cup to the stiffer cup for single bar stone-chip repairs or to change the crack-opener into a Star Flexor.
