Although I didn't expect it... the color shined again as if it were new and after 5+ washes so far it hasn't come off. On a friend's car where I tried it with very worn paint, it polished it slightly, yes, it didn't restore it, but after all, it doesn't claim to do so in the description—if something needs painting, it needs painting, period. In short, it does its job in the visual aspect clearly and it stays on, it's not like wax that comes off with the first wash, that's the main difference and innovation. I did the whole car plus another part I mentioned earlier and there's still plenty of product left. Do not spray directly on the car, apply it either to the special Sonax sponge or to a cloth

Very good. It creates a film that repels dust and water. I applied it a month ago and it lasts.

Update: 18/1: almost after two months of application - only one coat - and washes only in self-service car washes (not at all friendly for the protection) or the protection holds strong! The car cleans easily with just a pressure washer, even with fresh salt - snow at a ski resort and mud afterwards with just one wash in self-service using only a pressure washer it cleaned!! In the first wash that I will do with a bucket and mitt, I will apply another coat of protection.

Former amateur detailer, after years I'm gradually getting back into it! AMAZING protection, we'll see how long it lasts. To the one who says it's not enough for even one car, he probably started spraying it on his car, which is wrong!!! I did one C-SUV and one small car (VW UP) and there's still half a bottle left!
Incredible hydrophobicity and something that no one has mentioned hides a lot of imperfections in the paint (spider web), it goes and fills them in, resulting in hiding them and giving you better shine

Initially, it only goes through the entire car once and not 5-6 times as advertised. Secondly, it clouds the color and comes off very difficultly with washing and requires a very good wiping.

Excellent! The water simply glides, yes if you leave it, it can leave marks from salts as mentioned, but they disappear immediately. Stains disappear without causing any damage. A real shield. Hopefully it will last not 6 months as it says but 3. For its price, it's a steal.
I passed a big car, a small one, and it still has more than half left.

Update 1: After 2 months, the water still glides like the first day, just the depth of the color wasn't the same as in the beginning, after about 15 washes and several rains. The positive thing is that it has enough quantity for at least 6-7 times. It's excellent.

P.S. In a test I did, it protects from scratches - spider web creation from a cloth with dust.

It is the most durable thing that exists. It didn't come off even with the strongest soaps. It has extreme water resistance, which is both good and bad. For me, it's bad because water droplets remain and leave marks. It left many shadows on the black color, maybe I applied too much. However, I would buy it again to use it as a base and put something else on top (hopefully it becomes a topping)

The entire car became a mirror and the color shone very much and the windows incredibly clean when you do them inside out you save a lot of expenses and the result lasts easily for 4-5 months.
It does the job and with great ease. The price is worth it considering the result.

Easy to use, sacrilege the money it should cost much more with what it offers you, lifesaving material for me, I prefer it from now on with closed eyes

It is really very good, it doesn't even stick to dust and it is also very good hydrophobic. Finally, it creates a perfect film that has a very nice texture. I finished one of the two I had bought and I will buy two more to avoid shipping costs because there is nothing like this in Corfu and since I am in Athens now, I will also get a bonus gift.
