2 stars because after application it leaves a haze on the glass no matter how much you wipe it. I am simply disappointed because the glass has not cleared up for 5 months :(

Amazing product. From 50km/h and above, raindrops are removed on their own without the need for windshield wipers. The hydrophobicity it provides helps the windshield stay clean even at lower speeds with minimal use of the wipers. The application is simple and easy. In such products, the key is good surface preparation. Before applying, I cleaned the windshield well, followed by clay bar, polishing with carpro ceriglass using the corresponding pad with a da polisher, and finally ipa 50%. The result is excellent.

It makes the glass extremely hydrophobic, but not to the point where you won't need windshield wipers and the drops will disappear on their own at 50 kilometers (well, that goes without saying, but many people say it). What it helps with, in short, is that the windshield wiper will easily repel water.

It did what it promises. After a good cleaning, I applied it according to the instructions. Easy application with the sponge, then I removed it with a microfiber cloth. The next day, I poured water on the glass and I didn't expect such a good result. The question is how long it will last. I believe that the packaging is enough for at least 10-15 uses on the windshield

Purchased a week ago for amateur use. Applied to both new and older models in an environment with high humidity. Instructions were read thoroughly and application was done.

- Very good windshield cleaning first and then application of the product with the gray sponge (included), using circular motions.
- The entire surface was covered and the material was left on it for fifteen minutes.
- After the fifteen minutes, the entire surface was wiped with a slightly damp cloth.
- Dried lightly with a dry cloth.
- Requires a few hours (personally left it for one hour) without contact with water for the necessary bonding of the product.

Results:

At speeds of 70 kilometers/hour and above, the windshield wipers will be used minimally. At lower speeds, there is a difference in the amount of residue retained on the glass.

It's worth it!

It adds a hydrophobic protection to the glass and protects it from dirt and water. When you are on the road at high speed and it's raining, you no longer need to have the windshield wipers working at high speed as enough water slides off and away from the glass.
