Editing Windshield (section)

===Location===

Some damages are very difficult to repair, or cannot be repaired:
* on inside of the windshield
* deep damage on both layers of glass due to solar absorption or oxidation.
* damage over rain sensor or internal radio antenna
* complex multiple cracks
* very long cracks (i.e. over {{convert|18|-|24|in|cm|round=5|abbr=in|order=flip|disp=or}} long)
* contaminated cracks
* edge cracks

In cracked windshield repair, air is removed from the damaged area on the windshield with a specified vacuum injection pump. Then using the injection pump, the clear adhesive resin is injected to replace the air in the windshield crack. The resin is then cured with an ultraviolet light. When done properly, the damaged area’s strength is restored, as is 90–95% of the clarity.
