Even a small windshield crack can spread quickly if not managed immediately. You can stop windshield cracks and prevent serious damage by addressing the issue with a simple household solution.
Clear nail polish and super glue are both practical options for stopping a crack in the windshield from spreading. Here are a few quick tips for addressing the crack as soon as possible.
1. Wipe down the entire windshield with a microfiber cloth.
This will remove any debris on the surface. Take care in wiping off the cracked piece of glass. Do not apply much pressure as this could cause the crack to grow.
2. Apply window cleaner on the windshield.
Wash the windshield thoroughly and dry it with the microfiber cloth.
3. Fill the crack with nail polish or super glue.
Carefully apply the clear nail polish or super glue directly as glass crack filler.
4. Cover with clear packaging tape.
After the polish or super glue has dried, apply a piece of packaging tape to keep dirt and debris from affecting the crack.
Keep in mind that this is only a temporary solution that will give you time to purchase a windshield repair kit.
How Much Do Windshield Repair Kits Cost?
Windshield resin repair kits range from under $10 to over $200. The variety in price is directly linked to the amount of windshield repair you are interested in handling yourself.
A $10 kit works well on smaller cracks. It utilizes a resin kit that requires very little curing time and dries clear. This process will prevent further cracks, but does not always alleviate the crack completely. It will most likely still be visible, but is only a cosmetic issue.
The high end windshield repair kits require more effort and skill in application. These kits use a vacuum method that replaces air in the crack with high-quality resin. This type of resin is cured by utilizing a UV light that will strengthen the previously broken glass.
After the repair is completed, you will use a glass polishing tool to finish the job. This process will fill and buff out any remaining faults in the windshield.
Here’s our review of the best windshield repair kits on the market. We think you will find it to be useful in choosing the right application for your particular situation.

The package contains enough product for one repair. This repair kit is offered in two versions – large and small, depending on your specific needs.
For Best Results
First, read the instructions twice and watch the 5-minute video of the company on You Tube (search for “Blue Star Windshield Repair”). The video makes clear certain things: “tabs aligned” means aligned rotationally, not vertically.
In addition, there should be some adhesive pad tab sticking up above the pedestal tab when the latter is perfectly centered on the adhesive pad.
For best results, you should take a very methodical approach and make sure the pedestal is FIRMLY attached to the adhesive pad, and that the pin valve is REALLY sealed well.
Next, you should let the resin set under pressure in the pedestal for two full hours, not 20 minutes as recommended.
Finally, let the resin cure under the curing film for two hours on a day with passing clouds, not the 15 – 60 minutes recommended in the instructions leaflet.

It can effectively repair a bulls-eye damage as big as a 1-1/4 in. Based on the dimension and shape of the applicator, the Permatex 09103 is definitely not the best type of windshield repair kit for repairing cracks.

Factors To Consider When Buying A Windshield Repair Kit
If you plan to go shopping for a windshield repair kit any sooner, you should consider the following key factors:
1. Shape Of Damage
Which windshield repair system will work best for you depends on the specific shape of the damage you want to treat. However versatile the solutions reviewed above may be, no system works equally well on just any sort of window crack.
2. Resin Quality
Not all resin types used in windshield repair kits are of the same quality. Some repair kits boast a higher-grade resin that is a bit denser, and it also leaves a transparent finish which blends perfectly with your windshield after the repair.
Watch out, because a poor-quality resin will cure in a yellowish color which will make it apparent that you have been trying to repair your windshield on your own.
3. Temperature Sensitivity
Since the repaired windshield area will most likely stay in direct sunlight for an extended period of time, it also needs to have a reasonable sensitivity to temperature. Check your instructions for any mention of temperature.
Bear in mind that some resin formulate may require a specific temperature, as well as exposure to direct sunlight, so as to cure properly.
If you are looking for something that will help you to get rid of direct sunlight inside your car consider buying the best windshield sun shades. They have a reflective surface to bounce the light back, reducing the interior temperature. They regulate car temperature while summer, decrease inside temperature and protect from UV rays.
The quantity of the active substance in your windshield crack kit is important, especially if you are planning to repair larger or multiple windshields.
On the other hand, if you need the kit for one-time repair, the quantity of the resin is irrelevant. In most cases, a 1g resin tube is enough to completely repair a small windshield crack.
5. User Friendliness
Some windshield repair kits are easier to use than others. Ensure that your windshield repair kit comes with an instruction manual that will show you how to proceed.
Your windshield repair kit must also come with an applicator that will allow you to quickly and easily position the resin exactly over the cracked area of your windshield.
How To Use a Windshield Repair Kit
Each windshield repair kit comes with specific instructions that will help you get the most out of the product. However, here are a few steps that are part of any windshield repair.
1. Clean the windshield.
In order to obtain the best results from your repair kit, begin with a clean and dry windshield.
2. Read and follow the directions for the kit.
Before using the resin repair kit, read the instructions in their entirety. Some kits require additional supplies and tools. Be prepared ahead of time so you don’t have too stop in the middle of the project to gather everything you need.
3. Move your vehicle to a moderately cool place before repair.
Cold air causes glass to contract. Hot air makes glass expand. It’s important to complete the repair in a place where the temperature will remain the same throughout the entire process.
4. Apply the resin and allow to dry.
Repairing the windshield with a kit will allow you to see if the problem is resolved or if seeking professional services is needed. Depending on the damage, replacing a cracked windshield may be your best option.
5. Remove excess resin.
It’s possible that you will have extra resin remaining on your windshield after the project is completed. In that case, use a razor blade to scrape it off. Then, use cleaner to ensure that you have completely removed it.
6. Examine the windshield.
Take a look at the finished product and see if you are satisfied with the results.
