Tech Tip: Repairing Damage with No Impact Point

In this video, we demonstrate how to repair windshield damage that has no impact point.

The technician begins by probing the damaged glass to check for moisture and debris. Once the technician is confident there is no moisture or debris in the damaged area, he proceeds to the next step.

After determining that there is no impact point (surface damage) the technician drills half way along the crack, or into the largest air pocket, using caution not to drill into the laminate. This will create a pathway for the resin to flow into the damage. The technician then brushes the loose debris from the damaged glass.

Next, the tech attaches the Delta Kits Bridge to the glass, and injects the Delta Kits recommended amount of MagniBond Resin into the newly drilled area. You’ll note that the resin seeps out of the damage at the surface of the glass on the first pressure cycle, proving resin has displaced all of the air in the break. In this case there was no need to do a vacuum cycle and in fact, doing so would actually draw air in from the surface and compromise the repair. There will likely be times when it may be necessary to go through the Delta Kits recommended series of pressure and vacuum cycles (see “How to Repair Windshield Damage” video), but this is a perfect example of an instance when a repair system that relies on high vacuum is completely ineffective.

Once the resin has displaced the air in the break, the technician applies the pit resin, curing tape, and UV light to begin the curing process. After the resin in the damaged area has cured, the technician scrapes the excess pit resin off with the razor blade. Voilà! You have mastered the pit-less damage and have restored the structural integrity of the windshield.
