He did the repair perfectly. It exceeded my expectations. By faithfully following the instructions and videos from the internet, the result was professional. Attention, there are two versions of the kit: in one, the syringe goes in and out completely in the plastic holder, while in the other, the syringe has a cap that goes in and out. Fortunately, I had seen videos of both versions beforehand and knew what was going on because in the kit I received, the instructions referred to the version with the cap but the syringe was of the other type. That is, you couldn't follow the instructions that came with the product, basically you wouldn't know what to do. This was the only negative that might make things difficult for some.

If you follow the instructions exactly (which are in English, but you can see the process roughly on YouTube), it works. The case I used it for was on a 2016 Yaris, where the windshield, I don't know how, got hit and developed 2 pits with a crack between them, about 22mm apart. The impact was very noticeable to the touch, even the wiper left some small marks on the radius of the impact. I followed the process very closely and the result can be seen in the 2 photos before and after (the after is the one with the blue around - reflection of the sky). The pits are still visible, but after the final cleaning with the scraper included in the package, it is COMPLETELY smooth, you don't feel anything to the touch and the wiper works perfectly. In short, the job was done and I won't need to do anything else. One last thing, in some reviews of similar products, it is said that the windshield becomes cloudy locally after the repair. This is not the case with k2. I recommend it on the condition that you have the patience for the repair (count on over 2 hours)
