When there is a crack or chip in your car’s windshield, it is pretty common to be worried about the damage. One of the most common repair methods is resin injection, which fixes your glass without replacement. This process is fast, cost-effective, and quite convenient. That’s why people choose it as their first option.
But when we talk about resin injections, one question often crops up in our minds. And the question is, how many times can a resin injection be used on a windshield? Is it safe to repair the windshield repeatedly, and if so, when does car windshield replacement become necessary? If you want an answer to these questions, read this blog till the end.
What is Resin Injection?
Resin injection is a windshield repair technique in which a special liquid resin is injected into the glass chip or crack. This resin fills the damaged gaps and is then hardened with UV light to strengthen it. This prevents the crack from growing further and restores a significant amount of clarity to the windshield.
This process of repairing windshields is often used for small chips, bullseye cracks, and minor damage. The main benefit of a resin injection is that you don’t have to replace the whole windshield after small damage. It helps save not only money but also time because replacing a car windshield is labour-intensive work.
Factors That Affect the Number of Repairs
The number of times a windshield can be injected with resin is not fixed. It depends on the windshield condition, the type of damage, and previous repairs. Here are the factors that may affect the number of times a windshield can be repaired:
- Size of Damage: Small chips can be easily repaired, but big cracks are hard to repair.
- Type of Damage: Bullseye, star, and combination cracks all have different behavior.
- Location on Windshield: Repair is limited on the edges and the driver’s line of sight.
- Previous Repairs: A lot of resin injections can weaken your car’s windshield glass.
- Structural Integrity: If the glass strength is compromised, damage repair is not safe.
How Many Resin Injects are Typically Possible?
In general, a windshield can have multiple resin injections, but only one proper repair is recommended for every damage spot. It is possible to repair small cracks or chips individually until the overall strength and clarity of your windshield glass is not affected.
But if resin is injected into the same spot repeatedly, it can compromise your glass quality without providing any reliable solution. Also, if the damage is spreading or the spot of damage has already been repaired once, windshield replacement is considered a better option afterwards.
Tips to Extend the Life of Your Car Windshield
If you want to keep your windshield safe and damage-free for a long time, timely action and a little care can help a lot. You can avoid small cracks and chips with small habits and prevent them from spreading. Here are some tips to help you extend the life of your car windshield:
- Repair Chips ASAP: Never ignore small damages, as they can spread faster than you think.
- Avoid Extreme Temperatures: Don’t let very hot or cold air directly on the car windshield.
- Maintain a Safe Distance: Avoid tailgating, especially when you are behind large vehicles.
- Drive Slow on Rough Roads: Rough roads put unnecessary stress on your car's windshield.
- Clean Properly: Avoid harsh chemicals; instead, use a soft cloth to clean the car’s windshield.

On the Final Note
Resin injection is an effective and budget-friendly solution for small windshield damage. But this windshield repair method has a practical limit. It is not safe to repair the same crack or chip twice, especially if the strength of your windshield glass is already compromised. That’s why the best approach is to repair the windshield damage at an early stage and prioritize occupants’ safety.

Repeated repair on the same spot can:
- Weaken the glass
- Cause crack spreading
- Reduce visibility clarity
- Lower impact protection
Q. How do I know if my windshield’s structural integrity is compromised?
Here are the signs that repair is no longer safe:
- Crack reaches the edge
- Crack keeps growing
- Multiple cracks/chips nearby
