Windshield cracks are one of the most common troubles faced by vehicle owners. Many owners consider this problem a small one and don't realize that if they are not careful, the crack may spread swiftly and increase your cost of getting the auto glass fixed. To stop a windshield crack from spreading, you can try the following methods:

1. If you are a DIY kind of a person, you can buy a windshield repair it from a local supply store selling automotive parts and seal the crack yourself within a few minutes by using resin. It will not only protect the glass from outside elements but will also reduce stress on the glass. This can be the first pass at a fix before you see an auto glass repair specialist. 

2. Another method of preventing future damage to auto glass is to use super glue to fix the small cracks. Just remember to spread out the glue evenly, as it will hold two sides of a crack together and ensure that it doesn't grow larger.

3. In case you don't have much money to spend on repairing the auto glass, you can clean the crack and apply loads of clear acrylic nail polish on the inside and outside. Be sure to include the areas where the crack is more likely to spread.

4. Many people know that heat can damage the crack further, but most of them don't realize that snow or heavy rain are equally dangerous. So, you should always park your vehicle in the shade or in a parking lot or garage whenever possible.

5. If the aforementioned ideas haven't worked for you or you aren't that hands-on kind of a person, then you can get advice from a windshield expert in your locality. Sometimes, you may get the right advice and do it yourself by asking the expert to provide you with the right tools.

The best way to deal with a windshield crack is to let an expert fix the auto glass for you. It might cost a few bucks, but you will still be able to save a lot of money that you might have spent by waiting (as the crack might have gotten bigger with time). You may also get a guarantee on the quality of service provider, which ensures that if the windshield is cracked within a decided time span, you won't have to pay the expert again to fix it.
