Rain-X Windscreen Repair Kit, white/clear

I don't usually bother with reviews unless the product smashes your expectations out the park . . . this is so easy to use and I would say on a bullet style stone chip with fine cracks emulating from the centre it visually reduced noticeability to a point where you would struggle to find it unless you knew where the stone chip was. It removes the obvious 'white' area that reflects light where the damage is. The ease of application, price and results I can't fault - I can't recommend enough! I'm annoyed I didn't take a 'before' pic but loaded up one I found represents the damage I had - but the after is a shot I took (sorry it's blurry) at an angle to show the repair at its worst. Shows clearly what improvement can be made where the resin seeks out and fills the 'open' chip/cracks in the damaged glass removing the chance of light entering - it's the light reflecting in the damaged 'open' glass that makes a stone chip look so bad.

Tried this on my A200 after I got a stone chip and a couple of cracks radiating from it, some of which were getting longer. Unfortunately it didn't seem to take to the windscreen. I am not 100% sure but I think Mercedes windscreens have a film over the top of them. Or maybe just the sport version because of the tinted windows, I am not sure. So worth keeping in mind. The instructions were very clear and easy to follow. The suction cups really need to be pushed down hard to get them to stick, which was an issue for me, because of where the chip was. I had no choice but to have the suction cups going over the cracks, so I was very reluctant to push them down too hard. This did lead to various suckers popping off the windscreen at various points. Everything went as expected, curing strips worked great to dry the resin in the time stated and was fairly easy to scrape off with the included razor. Loses one star because it didn't work for me (but again that is probably for the reason outlined above, so I am not sure if it can be faulted for that. But possibly a bit more information could be given to check if you potentially have a windscreen that this item might not work with due to the manufacture process.) I have no doubt that if it wasn't for unique makeup of the windscreen then it would have done the trick. Definitely worth a try at £10 to save you having to pay your glass excess of ~£75 if you need your full windscreen replaced, which I now have to do. Not to mention the potential issues that come with getting a fitter that will do a good and proper job. They will never be as good as what the robots have done in the factory unfortunately. Hope this helps!

One of the best products I have bought for my car. I got a stone chip and tiny hairline crack after a 4x4 driver thought he was king of the road in the snow and went flying up the fast lane while throwing up all the rubbish off the road. I could my get an appointment with autogalss for approx 1 week so bought this so it didn't get worse. I must admit I was very sceptical of this product but thought it was worth a go. Well just say that I am more than impressed with the results and you can barely notice the chip now. If you follow the instructions exactly as they say then it will 100% work. I took a little longer to do it than the times in the instructions due to probably using a bit much resin and it is also 0 degrees outside so not took longer to cure which is no fault of the product. I still have plenty left over for further repairs so well worth the money. Would highly recommend it to anyone. After reading some of the reviews I would just like to add a couple of things as I think some people have set their expectations a bit high. My stone chip and crack is barely visible but yes it can be seen. This is not some miracle product that will give you a windscreen looking like new. If you want the chip completely gone from vision then I'm sorry but this will not give you that and only a new windscreen would fix this. I have seen others saying that there is not enough liquid. I can't say how others have been applying it but my chip was fairly large and even using more than the insructions say I was left with plenty to do more. The final complaint is that the adapter and plunger is flimsy. I'm a heavy handed sort of guy and I had no issues with this what so ever. Please remember this is a £10 fix as opposed to a new £500 windscreen so while it's not going to give you a new windscreen it does a dam good job for £10.

Be warned there is a long instruction sheet to read! Basically you position the suction cups over the chip. Screw in the plastic tub part squirt in the magic fluid. Compress this with another plastic tube. Wait 5. Then remove the whole lot and bin it. Leave to dry in the sun with a plastic sheet over. The product is good and did fill a chip on my windscreen quite well. It loses stars for being very wasteful as it all goes in the bin at the end of the process and for it being really fiddly to do. You also have to make sure you do it kn a sunny day.

Right so here my review. After waiting for so long for a nice sunny British weather I have finally managed to get it done. First of all I want to make it very clear that it doesn't work, I'm not sure how this has so many good reviews but it does not work. Since I bought it, I had to wait about 2 weeks for a good weather to get it done, until then I read the instructions about 10 times, along with YouTube videos. So by the time I went and done it I already knew the steps by heart. Nevertheless, on the day that I did it, I actually read the instructions again as I was doing it. According to YouTube videos, as soon as you apply the resin, it should fill the bullseye and the crack, I went inside the car to look from the inside and it didn't do anything. Anyway, I gave the benefit of the doubt and let it dry. Still nothing. Then I removed the device, applied the additional resin and covered it with the plastic film provided. At this point the car was in direct sun light to dry. It says to leave it for 10 minutes, I left it for 30 minutes. Removed the film, scraped the resin out and voila, nothing has changed, bullseye still there along with the crack. The total area that needed covering was less than a 1 pence coin. So this product is a big no no from me.

My problem was a rock-hit on the windscreen 6 months ago which created an impact that had a centre point and two cracks on either side, The overall length of the cracks was around 15mm (just over half inch). After being quoted £160 by a popular auto glazier, I thought I'd try this first. In short, this stuff must be using some kind of witchcraft, the results are essentially flawless. I read the instructions, pretty simple process (assuming you can get some sunlight). The final step of the process is cover the repair up with a small transparent plastic sheet to assist with the curing process - my problem is I couldn't actually see the repair by this stage because it was almost invisible! This crack had to be fixed because it was in the driver's view and a failure on the MOT, however the process is so simple and good that I'll be using it on a couple of small cracks on my other car that are on the passenger side and have been ignored for years. I don't now what kind of results you'd get for a long crack but certainly for my kind of impact, it is a deeply impressive product.

I do not think that this product is very good for the repairs that I had in mind which was to correctly fill and treat small chips and pits in my car windscreen and side window owing to stone chipping et-al. Possibly better employed to be drawn into small cracks and splits in vehicle glass because the liquid has low viscosity enabling the fluid to be pulled in. For chips in my humble opinion would require a higher viscosity so it would not run on vertical or near virtical and curved surfaces.

After having a small boulder hit the windscreen I had was left with nice chip, the biggest problem I find is that the chips ruin wiperblades very quickly. Of course you can get a windscreen repair specialist to come to your house but nowadays that can affect insurance and you have to pay an excess. So I thought I would give this a shot, I watched a few online videos for tips and it seemed easy enough. The results are very good! Although the chip isn't invisible it's now barely noticeable but the most important thing (for me) is that it's undetectable through touch so no more ripped or damaged wiper blades. There is also plenty of product for quite a few chips so once you have used it pop it in the bottom draw for the next chip or spread the cost over a few vehicles. One tip though, it says leave it for 6-10 mins in sunshine to let it cure. I recommend 30-40 mins (due to the good old British weather) so it's fully hardened.
