How do you Stop a Crack in your Windshield from Spreading?
A crack in your windshield is a very common issue that most car owners will face at some point. The crack may start out as a small hairline but can easily grow into a large spider web due to impact, weather, and age. However, there are many ways of stopping the crack from spreading and protecting yourself and others on the road.
Ways to stop your windshield from cracking
There are basically three different types of damage you can do to your windshield — rock chips, cracks, and star damage — and each requires a method to fix it. Rock chips are smaller than cracks (measuring only 1 inch) and look like little craters surrounding the actual chip. These also can be repaired without removing the entire windshield itself. A crack can be repaired by using clear resin which is injected into the affected area to stop the crack. However, star damage (cracks that form a star pattern) cannot be repaired and will require replacing your windshield. Of course, not everyone has the time or money for these expensive procedures; if you don't want to spend hundreds on fixing your windshield, here are some fast fixes you can make at home:
Using toothpaste
Yes, it may seem like an odd idea but believe it or not, this does work! By taking some non-gel toothpaste and rubbing it around the affected area of your windshield, you can cover up cracks and chips which help stabilize them so they won't spread further. The reason this works is because of the silica crystals found in toothpaste. These crystals are very similar to what glass is made of so when the paste dries, it will harden and hold together the cracks very well. However, it won't last forever so you'll have to get your windshield fixed eventually before it cracks completely.
Another option is using epoxy resin which can be purchased at any hardware store or automotive shop. You simply apply a thin coat over the affected area of your windshield and let dry overnight. When applying this resin be sure to take safety precautions such as wearing protective eyewear because once dried, this resin becomes like sandpaper when rubbed against by anything including clothing fibers (which may cause scratches).
Using potato
Believe it or not, this too does work. All you need is a potato and some toothpicks, then simply carve out small circular shapes in the potato to create a mold. When you're done, fill it with hot glue or silicone sealant and place gently onto the cracks in your windshield. This will stop rainwater from getting into the crack and causing more damage which can cause leaks while driving.
The best part about these homemade fixes is that they are super cheap compared to having your windshield fixed at a shop. However, one disadvantage of using epoxy resin or chips from potatoes is that it may not last very long since most household materials aren't manufactured for automotive use; however, if you match up all three of these tips together (epoxy resin, toothpaste and using a potato), you'll have a strong hold on stopping cracks from spreading. But by far the best option is to get your windshield fixed as soon as possible, whether it's at home or by a professional service technician. There are many risks including not being able "to see what is going on around you clearly" and potential injury to others if the crack becomes too large.
And remember: there is no substitute for a properly working windshield that prevents damage to yourself and others. Be sure to remove any material left over after the chips, cracks, or star damage is repaired so they don't interfere with your visibility. This will ensure both safety and longevity of your vehicle.
However, it still does not hurt to experiment with the different materials in your refrigerator to see if they work. Just be careful about what you try in case of potential or unexpected side effects.
Lastly, you could also check with your insurance company to see if they offer any discounts for fixing chips and cracks. If so, you may not have to pay hundreds of dollars out of pocket.
