How to stop a crack in a car window?

How can I stop a crack from spreading on a car window? I noticed a small crack in my windshield this morning. I’m worried about it spreading and don’t want to have to replace it.

Oh no! It’s a good thing you caught it. The wrong crack at the wrong time can spread at a moment’s notice. Ideally, you’ll probably want a professional to take a look at it sooner rather than later if it’s a decent crack.
In terms of temporary fixes, these are your best options:
  • Windshield repair kit: Normally, these come with an adapter and resin. Apply the resin on the crack and around it.
  • Super Glue: On each side of the crack, apply super glue and pressure. Doing so will force the glue into the seams of the problem spot.
  • Nail Polish: Much like applying the glue, do the same with clear acrylic nail polish.
None of these solutions are long-term fixes, and if possible, take the windshield in for inspection. Sometimes glass or auto repair shops can fill a crack, preventing the need to replace the window or windshield completely.
If you frequently drive on gravel roads or have gotten windshield cracks before, consider adding comprehensive coverage or full glass coverage to your insurance policy.
