Windshield cracks are dangerous. One crack can quickly cause the glass to become unstable, and it will only be a matter of time before the entire windshield falls apart or the visibility of the road is severely, and maybe even fatally, compromised.
If you find yourself in an unfortunate circumstance, the best thing you can do is prevent the crack from spreading. If the crack has already occurred and is likely to spread, follow these tips to stop a windshield crack from spreading.
Creative DIY Solutions
A cracked windshield can be a serious liability, but if caught early enough, the damage can be mitigated. It is important to thoroughly clean the windshield with a soft cloth and glass cleaner first before applying the following solutions:
Windshield Repair Kit
The repair kit typically has a syringe filled with resin designed to fill the crack and seal it against the elements. Once the resin is in the crack, a curing light is placed up against the windshield on the exterior side to allow the resin to harden and form a solid seal. Do not drive the vehicle until the repair is complete, as the vibrations from driving could cause the crack to spread.
Clear Nail Polish
Use a fine brush to apply several coats of clear nail polish over just the crack, making sure to seal the edge of the crack. After the polish is dry, apply a few layers of clear packing tape on the windshield above and below the crack. Leave the nail polish alone to cure the crack, allowing it to fill the crack and harden.
Make sure that the crack is completely clean and dry, as dirt, dust, and moisture can prevent the glue from bonding properly. Squeeze a small amount onto the crack and spread it evenly with a paper towel. Once the superglue has had a chance to dry, it should be able to prevent the crack from spreading further.
Sand the area around the crack, being careful to remove any additional dirt or debris. Fill the gap with an epoxy repair filler and then let it set. While epoxy isn’t the most aesthetically pleasing, it will provide a longer-lasting and seamless repair.
Once dry, apply a clear coat to the area to further strengthen and seal the area. Read the instructions on the epoxy to allow adequate set time to ensure its durability.
Automotive technicians use specialized tools to inject a special resin into the crack, filling it and creating a strong bond. Additionally, auto glass repair technicians can apply a layer of protective film over the repaired area to act as an additional barrier against further damage. The film can be purchased at most auto parts stores and is relatively easy to apply.
Professional solutions also include windshield replacement if the crack is too large. The professionals use the best adhesive and seals to ensure that the new windshield will last and offer the necessary protection for the vehicle’s interior.
