The best way to stop a crack in the windshield from spreading is to repair it as soon as possible. Even if you're on the go, you can still take steps to fix the issue. Start by cleaning the windshield with a car window cleaner and paper towels. Then, as a low-cost solution, apply clear nail polish or super glue to the chip.
Let the polish or glue dry, then place a piece of clear adhesive tape over the area to keep dirt out until you can get it repaired professionally. Who knew you could temporarily fix a windshield with these everyday items?When closing car doors, do so slowly and carefully to reduce concussion forces. Gravel roads and patches are a surefire way to end up with a broken windshield. Whenever possible, avoid gravel roads at all costs.
This can be done by steering clear of areas where trucks distribute gravel, since the tires of the vehicle in front can easily lift small pieces of gravel and those pieces can project directly onto the windshield. If you see a gravel truck on the road, do your best to stay away from it. When parking in open areas, you expose your car to a wide range of objects that can hit the windshield, from flying debris, hail, icicles, etc. To prevent these items from breaking the windshield, park in covered areas whenever possible. Even if it's not completely covered, garages and vehicle tents are better than no protection at all. If you act quickly and have it repaired by a professional, you may be able to avoid having to replace the windshield altogether.
Once your windshield has been fixed or replaced by an expert, you can go back to your regular activities. If your windshield cracks or splinters with a rock while traveling, you may not have time to repair your car windows right away. However, you can't let a broken windshield sit or there's a high chance that the crack will get bigger, which could make it impossible to repair. If you let a rock break and turn into a total crack, it's too late to repair it, but you should still replace the windshield as soon as possible. Unfortunately, super glue, clear nail polish, epoxy, and other homemade methods for windshield repair never work for long.
