Your Guide to Choosing the Best Windscreen Repair Kit
A small chip or crack in your car’s windscreen can quickly turn into a big, expensive problem. A good windscreen repair kit lets you fix minor damage yourself. This guide helps you pick the right kit for the job.
Key Features to Look For
When shopping for a kit, some features make a big difference in how well your repair works.
1. Resin Quality and Type
- UV Curing Resin: Look for kits that use a resin that hardens quickly when exposed to sunlight (UV light). This makes the repair faster and stronger.
- Clarity: The best resins dry clear. Cloudy or yellowing resin will make the repaired area very noticeable.
2. Applicator System
- Pedestal and Syringe: Most good kits use a pedestal (a small stand) to hold the resin over the damage. A high-quality syringe then pushes the resin deep into the crack.
- Vacuum Seal: The best systems create a strong seal around the chip. This seal pulls air out of the crack, allowing the liquid resin to fill the space completely.
3. Included Tools
- Check if the kit includes curing strips (small plastic films placed over the wet resin) and a razor blade for scraping off the excess material once it dries.
Important Materials in Your Kit
The parts inside the kit determine its ease of use and the final strength of the repair.
The Repair Resin
This is the most important material. It is a strong, clear liquid plastic. It must bond tightly with the glass. Cheaper resins may shrink as they dry, leaving a weak spot.
The Applicator Tools
Good kits use durable plastic or metal components for the pedestal and syringe. Cheap, flimsy plastic parts often break or fail to create the necessary seal.
Factors That Improve or Reduce Quality
Not all kits work equally well. Here is what makes a difference.
What Improves Quality:
- Complete Air Removal: Kits that effectively remove air from the crack result in a nearly invisible repair. Air bubbles are the enemy of a good windscreen fix.
- Thick Instruction Manual: Clear, easy-to-follow steps mean you are less likely to make mistakes.
- High Viscosity Resin: A slightly thicker resin often holds up better in larger cracks.
What Reduces Quality:
- Damage Type Limitations: Most DIY kits only fix small chips (like bullseyes) or short cracks (under 12 inches). Trying to fix large areas often leads to failure.
- Poor Sealing: If the pedestal does not seal well to the glass surface, air leaks back in, and the resin won’t penetrate fully.
User Experience and Use Cases
Using a windscreen repair kit is usually a quick job, but preparation is key.
When to Use It
Use the kit right away! Fresh damage is much easier to repair than damage that has sat for weeks. Water and dirt get into the cracks, blocking the resin.
The Repair Process (Simplified)
First, clean the area well. Next, attach the pedestal over the damage. Then, inject the resin using the syringe, often applying light pressure. After the resin fills the void, you cover it with a curing strip and let the sun harden the resin. Finally, you scrape the cured excess away.
User experience is generally positive when the damage is minor. If you follow the steps carefully, you can save money compared to visiting a professional.
Windscreen Repair Kit Buying FAQs
Q: What size damage can a typical DIY kit fix?
A: Most kits are designed for chips smaller than a quarter (about one inch wide) or short cracks usually under six inches long. Large breaks need professional attention.
Q: How long does the repair process take?
A: The actual application of the resin takes about 15 to 30 minutes. However, you must wait for the UV light to cure the resin, which usually takes another 10 to 20 minutes in direct sunlight.
Q: Will a repair kit make the crack completely disappear?
A: No. The kit will make the area much stronger and significantly reduce the visibility of the damage. You might still see a faint line, but it stops the crack from spreading.
Q: Can I use these kits on side or rear windows?
A: These kits are primarily designed for the laminated glass used in windscreens. While you might try them on tempered glass (side/rear), the repair may not hold as well because tempered glass shatters differently.
Q: What happens if I use the kit in the shade?
A: If the resin does not get enough UV light, it will not harden properly. The repair will remain soft, sticky, and weak. You need bright, direct sunlight for a successful cure.
Q: Do I need to drill the crack before applying the resin?
A: Some older or specialized kits might suggest this, but most modern, high-quality kits do not require drilling. The vacuum system is designed to pull the resin into the existing fracture points.
Q: Is the repair permanent?
A: A properly executed repair using quality resin is very permanent and prevents the damage from getting worse. However, if the glass is heavily stressed later, the repair might fail.
Q: What is the main difference between a cheap kit and an expensive one?
A: Expensive kits usually offer a much better vacuum/pressure system for air removal and use higher-grade, clearer resin that cures harder and looks less noticeable.
Q: Can I use this kit if the damage has water in it?
A: You must clean and dry the damage thoroughly before applying the resin. Water prevents the resin from bonding correctly. You should use rubbing alcohol or a thin needle to try and push out trapped moisture first.
Q: Are windscreen repair kits legal for inspection?
A: In many places, a professional, permanent repair on the main viewing area is acceptable. However, large repairs or repairs in the driver’s direct line of sight might still cause you to fail a safety inspection. Check your local vehicle laws.
