Most windshield cracks can be repaired if the crack is no longer than 12 inches. Stress cracks and edge cracks that intersect more than one edge cannot be repaired.
Check for irregularities. If you're at the front or rear of the car, look along the car to see if there are small dents. These can be seen as distortions in the reflection. If the paint is not smooth in one place, then this could be a place where there has been some damage. Dents as large as a coin can be restored by a panel beater. Dents that are not thoroughly repaired are often filled with polyester resin or fibreglass paste. Tap the surface, or go along it with a magnet. Know whether the panel is made of steel, not plastic, fibreglass or aluminum. If there are places where the magnet will not adhere, then in all likelihood, the panel has been repaired. Ask the owner why the part has been repainted?

Never pour hot water on your windshield. If you walk out and notice that your windshield is icy, you may consider pouring a large cup of hot water on the glass to melt the ice. This is actually a very bad idea. Large temperature changes can cause the glass to crack. It is best to turn on the car defroster and let the glass slowly warm up. The ice will melt away safely without damage to the glass.

So, what do you do if you have a high deductible and your windshield gets a chip or crack? windshield chip repair has been around since the mid 1970's. Most insurance companies wave the deductible for windshield chip repair, but what do you do if you have a crack starting at the edge of your windshield? If you call windshield repair shops you will find most shops will not repair a crack over 6 inches in length and they will almost always recommend replacement.
The majority of windshield replacement companies are able to fix chips that are 3 inches or smaller, as long as it is not directly in your line of sight when driving. This is because attempting to repair these cracks can cause some distortion, which might prevent you from seeing the road clearly. Also, a lot of states have laws that mandate that your windshield not have any blemishes.
