A windshield repair kit can fix small hairline cracks with clear resin and suction cups. Larger cracks may require professional repair or replacement. The owner must remove debris and follow instructions carefully for best results. Additional coats may be necessary for deeper cracks.

When repairing a windshield crack, the car owner will need a windshield repair kit that includes the resin to repair the crack along with the necessary tools to apply it. The owner places the included tool over the crack, and suction cups hold it in place on the windshield. Then he fills the crack with a clear resin and lets it dry. Once it has completely dried, the owner removes the tool and checks to see if the crack is less visible. If the crack is still noticeable, he can repeat the treatment as needed to fill it in and smooth it out.

Cracked windshield repair kits will only work for small hairline cracks and will work best on small dents or holes in the windshield. Larger cracks may not go away no matter how many treatments the homeowner applies. The best option for repairing a deep or long windshield crack, or one that is unresponsive to treatment, is to take it to a professional to have the windshield repaired or replaced.

To begin the process of repairing a windshield crack, the owner must remove any loose glass and other debris inside the crack. A small razor blade works to gently scrape away the crack. The windshield should be washed to remove loose particles and glass shards. Next, the owner should remove the tools from their windshield crack repair kit and should check the instructions, as each kit may differ slightly. The main tool with the suction cups should be placed over the crack so that the crack is visible when looking through the open center of the tool.

Once the tool is in position and firmly attached, the owner applies the resin to the center of the hole. The kit may come with other tools to properly apply the resin and remove air bubbles once applied. To finish fixing the windshield crack, the owner just needs to let the car sit in a warm, dry area and wait for the resin to harden.

The resin will harden into a thick, clear mass that will remain firmly trapped in the crevice of the windshield. After removing the application tool, the owner can decide if another coat of resin is necessary. Deeper cracks may need this extra layer to fill them completely. If the windshield repair kit is unsuccessful in repairing a windshield crack, the owner should have a professional view of the broken windshield and should inform the mechanic that they attempted to repair it with a resin kit.
