The chip has virtually disappeared with all that is remaining is the marking from the gel insertion. You cannot expect the chip or crack to completely vanish but it’s certainly a huge improvement.
How Does it Work?
Unlike standard glass, the windshield is a technological masterpiece. They make use of laminated glass, which consists of three layers and is capable of withstanding a lot of damage from debris on the road. The design also prevents shards of glass shattering in the event of an accident, which can be very problematic.
However, in the case of windshield chips, it means that they can be repaired fairly easily. As long as the chip or crack has not damaged the middle layer, it will is able to be repaired. The resin will fill the gap of the broken outer glass and evacuate air from the chip. If done correctly, the repair will be permanent unless it is chipped again in the same place.
How to Use a Windshield Chip Repair Kit
When it comes to using the repair kit that you have just purchased, the majority will use the same application steps, which include:
- Clean the work area and ensure that it’s free of dust.
- Use a razor blade to remove any debris or tiny bits of glass.
- Setup the applicator over the chip or crack.
- Add resin into the syringe.
- Use the syringe to slowly push the resin into the gap.

- Use a razor blade to remove any excess resin.
- Finish up by using glass polish to remove fine scratches.
It may look like a difficult task but you will be surprised to how easy it really is by using the correct DIY kit.
Types of Windshield Damage
Before purchasing a windshield repair kit, you will need to ensure that the chip or crack is repairable. As you can imagine, there is a variety of defects that can occur on your windshield but not all of them can be repaired. Below are some of the defects that can be repaired.
- Cracks that are no longer than 14 inches
- Bullseye chip that is no bigger than an inch
- Half moon/partial bullseye that is not larger than 1 inch
- Star break under 3 inches
- Surface pit that is less than 1/8 of an inch
- Combination break that is under 2 inches
There are other different types of damage that may occur on your windshield. Use the sizing of the defects as guidelines because depending on where the damage is may be an important factor. For example, most chips or cracks on the edge may not be repairable.
Replacement vs Repair
Depending upon the extent of damage caused by the chip, you will have to decide upon whether to repair or replace the windshield. Repairing the damage comes with it’s benefits (as discussed below) but sometimes the damage may be too much.
For example, if the chip is too large or has gone too deep, this would be difficult to repair. You may have multiple stone chips and cracks, which would make repairing them all a long process. However, due to technological advances in the resin used for the repair, you can achieve excellent results.
Benefits of Repairing
One of the main benefits of using a repair kit is of course the cost savings. A replacement windshield can cost thousands but even the best windshield repair kit within this article is a fraction of the cost.
During the replacement of a windshield, you will be required to break the factory seal. If the new seal is not applied correctly, it may reduce the safety and structural integrity. Using a DIY repair kit will not effect the factory seal.
Another benefit that is often forgotten about is the fact that you keep the OEM windshield glass. During a replacement, many companies may use a cheaper quality glass, which comes with it’s own drawbacks. You are able to check whether the glass is an OEM part by checking the specification on the lower right or left sections of the windshield.
How To Avoid Further Damage
If you are waiting upon your repair kit to be delivered or are simply avoiding repairing the damage, you should try to avoid further damage. The most common causes of cracks spreading is due to the windshield being subject to adverse temperatures. For example, if you pour boiling water onto a cold windshield and vice versa.
To avoid any further damage, you can use a windshield cover to protect the screen and maintain a safe temperature. Other tactics include using super glue or nail polish to prevent spreading but these are not advised when you consider the low cost of a proper repair kit.
Unfortunately cracked or chipped windshields are very common and hard to avoid when driving. Many will simply replace their windshield but not only is this expensive, it may get damaged again sooner than you think.
Using a repair kit for your windshield is a cost effective solution that require no professional skills to use. Most come with everything you require to fix chips or cracks and are a fraction of the cost of having your windshield replaced.
