Best Windshield Repair Kit

Last Updated on by

Windshield chips are pesky and annoying. They can be big or small and happen for a plethora of different reasons. Rocks and gravel from the road can be kicked up and mark up the windshield, large trucks can even kick debris up at your car or a ball could be hurdled by an innocent child and it crashes into your windshield, inducting a tiny crack. Sometimes, temperature fluctuations occur from hot to cold or cold to hot and this places a large amount of stress on the glass, cracking it. Inclement weather, such as hail, also can damage your windshield. Maybe you got into an accident and the windshield cracked slightly. Whatever the case may be, if the windshield is chipped, this could lead to a bigger and more costly disaster if left untouched.

Top Windshield Repair Kit

Depending on how bad the chip is in your windshield, the kit may be effective in repairing it. It should be noted that these kits are not designed to be a miracle complete fix to a full blown crack in your windshield. They are designed to repair and be sure that the damage does not get any worse and expanding. The kits will, if effective, hide the damage very well and will save you a big chunk of change in the long run.

Long cracks in the glass are not repairable with these kits, those will have to be fixed by a professional. However, look through a magnifying glass at the chip or very small crack. Any chip in the windshield glass that runs perpendicular to your surface of the windshield or at a very shallow angle is able to be fixed with these kits. Most kits are effective due to a product called resin. Resin is inserted into the crack or the chip to repair the damage.

It should be noted that right away when damage to your windshield occurs, the crack or chip should be covered with transparent tape for prevent any moisture or dirt from entering. The windshield should be repaired as soon as possible to prevent it from growing and spreading.

There are different shapes of damage that are usually fixable. Bullseye damage is round with a dark circle and an impact point, a combination break starts as a bullseye and has multiple characteristics, a crack is a single line and a half moon is a partial bullseye. Star break damage has multiple “legs” coming from the break and a surface pit is usually a super minimal chip. These are just some of the types of chips that are able to be repaired. Certain kits mention that they will only fix certain types of breaks, so it is important to be able to identify which break is similar to yours.

Buying Guide

When attempting to sort through these, it can get confusing and frustrating because in reality, they are very similar with only a few minor differences. It is important here to think about which method appears to be easiest and most effective for you, how much you are willing and able to spend and what kind of damage you have or anticipate possibly having. Here is a bit more of a break down to help you narrow down your choices and options.

Method

First, which method appeals most to you? If repair strips seem to be more effective or easier than utilizing some sort of injector, it would be recommended to look into the Automotive Glass Nano Kit as long as your chip or crack meets the size requirements. If you are looking for an injector with a pressure vacuum feature to be able to remove air and debris from the crack or break, the YOOHE, PDR or Blue-Star brand is a good option.

Price

We have a wide range of prices here, but the higher priced options seem to really stand behind their product and its effectiveness. With the Clearshield model, it is more expensive than the others, but it universally fixes all laminated glass and all cracks and chips, unlike some of the others. Keep in mind that sometimes, you do get what you pay for and it may be wise to invest a little more to avoid having to replace the windshield you already repaired in the future. 

Versatility 

Some of these repair kits claim they will be effective on all types of laminated glass and all types of damage and others are very specific in the type and size of the damage. Each is listed out in the product description. Do your best to match up the shape of the chip or crack and be sure before purchasing that the brand you choose is compatible with that damage.

Conclusion

When you are shopping for the best windshield repair kit, it can be confusing. Remember that if you do not go with a product that offers a vacuum feature to remove any air or dirt, to be sure to insert resin into a clean area. This area should not be wet, so if you use water to clean it out, be sure to thoroughly dry the area before beginning your repair at home. Hopefully, the damage you have matches up with the damage that is fixable with one of these brands and you are comfortable with the method necessary to complete the repair. This guide should have eradicated any confusion or concerns moving forward with your windshield repair. Good luck!
