My Top 5 Windshield Repair Kits

If you have experienced cracks or chips in your windshield, then kits made specifically to fix that problem can help minimize the damage and halt the spread of the cracks. The windshield repair kits work best immediately after the cracks appear. If you delay, dirt and water will fill the cracks, making it harder for repairs to work well.

Windshield repair kits reduce the time you would spend searching for a mechanic for fixing or replacing. You can do it yourself – as long as you follow the instructions – and your windshield cracks and chips will be hidden. By the way, I have a good step-by-step guide: How to Fix a Windshield Chip

1. Rain-X 60001

The kit consists of one gram of resin, curing strips, and a sleeved razor blade. It should be used the moment cracks appear and before dirt has accumulated. The resin will expel any air from the cracks and make the windshield stronger. The kit is recommended for cracks less than 12 inches long and for round damage not more than an inch in diameter.

You can use the Rain-X on all types of laminated windshields, but not where is the damage has penetrated more than one layer of glass. The kit offers excellent value for money because you can use the kit for multiple repairs.

The kit is great for people who have never used windshield repair kits before. There are clear do-it-yourself instructions that, when followed, ensure outstanding results. Once the resin is applied, your windshield becomes stronger than before. It is advisable that you be patient with the process —you should see a significant change in the glass after around 30 minutes.

Pros:

• Simple to apply
• Durable resin
• Can be used for multiple repairs
• Works on all types of laminated glass

Cons:

• Cracks can still be visible upon close inspection,

2. Clearshield Professional

This kit comes with everything from cordless UV light to 20 carbide drill bits; you have everything you need for proper repairs. Clearshield Professional Kit can be used to make more than 200 repairs. Only one person is needed for repairs.

The kit offers great value, considering all the extras in the box. It should not come as a surprise that most professionals who repair windshields use this kit.

Included in the large box are the following items: 8 inner O-rings, a toolbox, 4 external end seals, 100 curing squares, 10 razor blades, 1 collet, 1 drill set with battery, a drill and charger, a 30 ml thin resin bottle, and a UV light.

Pros:

• Kit has all you need for repairs.
• Offers great value for money
• Kit will make over 200 repairs.

Cons:

• Some of the items are basic items in most windshield toolkits

3. Permatex Windshield Repair

The kit has everything that you need to perform repairs without any help. Included are photographs to guide you in the process. If you have not used a windshield kit, then the Permatex 09103 could be the best choice for you because it uses a state-of-the-art delivery system that utilizes a spring lock feature; this means the manufacturers have done the mixing for you—all you need is to apply it.

The resin strengthens under sunlight, but you need to apply it in a shaded area. The resin offers a permanent cure to cracks. You can use the kit on laminated windshields, including bullseyes of up to 1 ¼ inches in diameter.

Inside the package, you will find 1 adhesive disc, a Permatex windshield repair syringe and plunger, 1 pedestal, 1 push pin, 1 curing pin, 1 alcohol towelette, and 1 instruction sheet.

• Being in the industry for a long time, the company has a well- established reputation
• You can apply the resin at any time of the day

Cons:

5. J-B Weld 2100 Windshield Repair Kit

The J-B Weld 2100 really shines when you’re looking to take a DIY swing at windshield chips without emptying your wallet. I had a quarter-sized star chip to repair, and for the price, it felt like a shot worth taking. The setup is straightforward, but you’ve got to read the instructions twice before diving in — this one is not for freestyling. Once you get the hang of the pedestal and syringe combo, the process becomes smooth enough, especially if you’ve got a warm, sunny day to help with the UV resin cure.

That said, not all repairs turn out equal. I’ve seen this kit minimize chip appearance quite well, but more complicated damage or deeper cracks might be beyond the scope of what this kit can truly fix. The resin penetration can be a little tricky depending on how well air is evacuated. A poor seal or minor mistake here can mean less-than-satisfying results. But when it works, it works impressively well — especially considering the cost savings compared to calling a pro.

Pros:

• Extremely affordable compared to professional repairs
• Good at minimizing visibility on small chips and stars
• Resin cures quickly in direct sunlight
• DIY-friendly with a bit of patience and focus

Cons:

• Tricky resin application if the chamber isn’t vented properly
• Less effective on larger cracks or poor quality chips

What to Look for When Buying a Windshield Repair Kit

Resin Quality Makes or Breaks Your Repair

Trust me on this one — I’ve seen too many DIY repairs turn into expensive windshield replacements because someone bought a kit with cheap resin. The quality of the resin is absolutely the most critical factor in any windshield repair kit. Good resin flows properly into the crack, cures clear without yellowing, and actually bonds with the glass instead of just sitting on top like a band-aid.

Look for kits that use optical-grade resin, not the watery stuff that some bargain brands try to pass off. The resin should have a consistency similar to honey — thick enough to stay put but fluid enough to penetrate deep into hairline cracks. I’ve had customers come back after using dollar-store kits where the “repair” looked worse than the original chip because the resin turned cloudy or started peeling off after a few months.

Application Method and Tools

Different types of windshield damage need different approaches, and a good kit should handle the most common scenarios. Look for kits that include both injection and bridge applicators — injection works great for bullseye chips, while bridge applicators are better for long cracks and star breaks. The cheap kits usually only give you one method, which limits what you can actually fix.

The suction cup quality matters more than you’d think. I’ve wrestled with flimsy suction cups that won’t hold pressure, and it’s beyond frustrating when you’re trying to inject resin and the whole assembly keeps popping off. Good kits have heavy-duty suction cups with proper gaskets that create a real vacuum seal. Also check that the kit includes enough adhesive strips or curing tabs — running out halfway through a repair is a nightmare.

Size Limitations and Damage Types

Here’s something most people don’t realize until it’s too late — windshield repair kits have real limitations on what they can fix. Most consumer kits can only handle chips smaller than a quarter and cracks shorter than 6 inches. Anything bigger than that, and you’re wasting your time and money trying to DIY it. I’ve seen people attempt to fix dinner plate-sized spider cracks with a $15 kit, and it’s just not going to happen.

The location of the damage matters too. Chips right in your line of sight might not pass inspection even after a good repair, and cracks that extend to the edge of the windshield usually can’t be fixed with consumer-grade equipment. Edge cracks have a nasty habit of spreading no matter what you do, so save yourself the headache and just call a professional for those.

Weather and Temperature Considerations

Don’t even think about attempting a windshield repair when it’s below 50°F or above 90°F — the resin won’t cure properly in extreme temperatures. Most kits work best between 70-80°F with low humidity. I learned this the hard way during a scorching summer day when the resin started setting up before I could even get it into the crack. Patience pays off here — wait for decent weather conditions rather than rushing the job.
