Rain-X Windscreen Repair Kit - Quick & Cost-Effective Solution for Cracks & Chips - Easy Application - Prevents Spreading - Strengthens Glass - 15-Minute Repair

***The kit I received was supplied with full English instructions. I suspect previous reviews had an older packaging without this.*** I’ll preface this review by stating I’m an ex windscreen repairer with 10 years’ experience in the employ of a well-known vehicle glazing company. I’m sure you can guess which one *cue annoying ad jingle*. I mention this to give context to the fact that I have a lot of comparison basis in regards to equipment, usage, results and expectations. Firstly, the concept and application is more or less identical, bar the Rain X kit not having active, external vacuum; it creates its own vacuum due to the plunger assembly. Aside from that, the procedure is the same: - Clear the surface of debris/glass fragments - Position resin port directly over the impact point - Apply resin - Apply plunger/vacuum - Wait for air voids to fill - Cover surface with resin & patch - Wait for full cure (external UV light, if available, would work wonders) - Scrape away excess cured resin - Refill surface if necessary and repeat curing stage (not always necessary) When I first saw these kits hit the market as a windscreen technician, I swiftly disregarded them as inadequate and a cheap mock-up from companies that couldn’t compete with the big players who have design patents and entire R&D departments dedicated to producing equipment for this purpose. After using this kit for the first time, I’m happy to report that I was mostly wrong. The resin filled the chip’s voids and cracks just as well as I would’ve expected my previous “professional” level equipment to do. Over the course of doing 10+ repairs per day, 6 days per week for 10 years, you get a feel for these things. In fact, the repair was so much simpler and accessible for the average car owner due to not needing any external vacuum compressors, airlines or power supply. Cosmetically, you can barely see the chip now and it was indeed very visible beforehand with multiple “legs” radiating from the impact point, full of air and very dark from certain angles. Now, you’d be hard-pressed to spot it if you didn’t know where it was. And we’re over one month in with no sign of degradation or cracks spreading so I’m confident the repair will hold. My only regret? In my enthusiasm to get the job done, I forgot to take before & after pics 🤦‍♂️ Finally, an important tip for those looking to DIY your windscreen repair: if the chip has been recently exposed to water/rain, wait until it’s completely evaporated from inside the chip before attempting repair. Bare this in mind before you wash your screen in an attempt to clean the glass beforehand - this is actually counterproductive. The reason for this is water will dilute the resin, prevent it from filling and displacing air in the break, and also prevent the resin from curing properly. You can tell if it’s full of water by a translucent, faintly milky appearance, whereas a dry chip will appear darker with more pronounced air voids. If in doubt, leaving it in the sun for a day if possible should do the trick. You can accelerate drying by using a hairdryer on gentle heat, but BE CAREFUL with this, especially in cold weather as thermal shock is one of the best ways to send your chip into a full crack. Also, don’t apply pressure to the chip or attempt the repair if the glass is hot, for the same reason. In summary, this kit works, is great value for what it can achieve, will repair multiple chips (and cracks, according to the instructions), and is more or less as good as a professional repair if you prepare correctly, as with any job. Hope that helps.

Don't expect this to make your damage disappear altogether - I purchased it not having this expectation, but rather to minimse the damage and help to strengthen three small areas of damage on my windscreen to stop them from getting worse. To be honest, I was rather surprised by the results - the product is easy to use and is quite good at hiding 80% of a small crack in the screen. You'll struggle to make too many inroads with large bullseye chips, but it does improve things and helps prevent spread. Given that professional repairs are ridiculously expensive, this is a decent alternative that will do 80% of the job for a fraction of the cost.

A very easy way of repairing a stone chip on your windscreen. The whole process took me around half an hour and I was truly amazed by the results. Clear instructions to follow - make sure you take your time to align the plastic device perfectly with the centre of the stone chip. This isn’t going to make the stone chip vanish completely but as you can see from the pictures it’s a vast improvement and it should therefore prevent the chip turning in to a crack. Highly recommend this product and there’s loads left in the tube for further use should you get another stone chip.

Such a well known brand, very disappointed that it didnt get into the cracks properly. Still, it is done now, and I cant change it. Funnily enough I was told the cheaper one was good, but I recognized the name and thought it would be better.

Follow the instructions and it works very well. We had impact from the bottom of the windscreen and the crack had spread for in a few directions. I knew I wouldn’t be able to fix it all so just concentrated on each leg of the crack and also the impact point. (Wiper motor was being removed and the arms had just squashed the corner of the windscreen) I highly recommend using a UV lamp. We used the nail one we had here, they are cheap enough. So I cannot comment on the sun doing the curing which is what the instructions say. The uv lamp worked a treat to cure the uv glue then you scrape off the excess. The overall finish was the crack seemed to disappear in some places, others it’s visible but it’s ‘sealed’ and the main impact site is sealed from the Elements. Overall a worthy purchase. On a single bullseye 🎯 crack I think you would get a brilliant result.

Razor and curing strips missing so unable to follow the instructions. Seal also broke during step 5 and spilt resin everywhere. Terrible

I recently got a small chip with 2 small cracks at each side of it (approx 6mm and 10mm) I previously used Halfords screen repair service on another crack a few months ago and they made the crack more obvious as well as scratching the glass around the repair so I decided to DIY this one, one downside is there are no English instructions but there are plenty of good tutorials on YouTube so no big deal, I think I used a little too much resin as it leaked out despite me tightening it up but in a way I see it as a good thing as it will give increased pressure to force the resin into the crack, I covered the repair with a black hoodie as I was doing it outside on a sunny day to allow it to flow into the crack for as long as possible, once the resin had cured it was easy to cut the excess off with the razor blade, the result was way better than I expected and I cannot find the repair from outside, there is a tiny shadow on the cracks when you look for them from the inside but not really noticable, I wish I had taken photos before to show how good the repair is. Definitely worth the money. EDIT I checked the repair after a couple of hours and it's now completely invisible, I also used some resin and a piece of the film to repair a chip in the glass on my watch which was caused by welding spatter, it has filled it in really well and is only visible if you look closely at the right angle.

Fixed the chip in both mine and my wife’s screen. Great product

Fungerar men man bör tänka på att ha bra UV-strålning när reparationen utförs. Minst 3,0.

Me resolvió bastante un piquete en el parabrisas, facil de usar.

Un sasso aveva prodotto un mezzo foro sul parabrezza, senza però produrre crepe. Sembrava una cacca di piccione. Ho seguito le istruzionui per ripararlo, ma ho applicato male il prodotto, bavando resina sul vetro. Sono intervenuto con una lametta e ho cercato di rimediare. Dopo 15 minuti .. il foro era diventato trasparente ... non si vede più nulla...

Super Produkt War sehr skeptisch , jedoch wurden meine Erwartungen Übertroffen . Riss in der Frontscheibe sehr gut verklebt. Kann ich empfehlen und würde es wieder kaufen.

Épatant. Testé sur 2 éclats dans mon pare-brise : Super résultat : il ne reste qu'une infime trace sur 1 des 2, mais c'est quasi indétectable. À noter qu'il faut refaire plusieurs fois les étapes 4 et 5 de la notice (dévisser la vis supérieure (pression), remettre une goutte de résine et remettre la vis de pression), jusqu'à obtenir un résultat parfait. Alors durcissement de la résine au soleil, gratter avec la lame de rasoir perpendiculairement au pare-brise. Je recommande.
