Our unbreakable, stronger than glass 1600 edge crack resin can be injected directly from this pressure syringe into the edge section of an edge crack.
How to use - Place the tip flush on the crack at the edge of the windshield. Use two hands. One to hold it firmly on the glass and the other to lightly push the plunger. Slide down the crack until the crack closes and no longer easily flows into the crack, which will be at least 6 inches. See our Blog of November 2017 for more instructions.
