It does EXACTLY what it promises.
You see the result and you can't believe it.
It helps a lot with cleaning and leaves a shine because there are no more water droplets anywhere.
It smells amazing and the scent stays on the car.
Just one observation. According to Autoglym, it would be good not to pour it on the windshield.
Also, according to Autoglym (and I agree because I saw it in practice),
there is no reason to use more than 40ml of product.
With a ratio of 40ml Polar Seal / 200ml water (and adjusting the valve of the washer in the middle),
it easily covers a large car.
There is no chance I will wash a car again without using it.

Amazing!!!
I found my health as soon as I used this product! No more rain anxiety!
Now I want it to rain!! I want it to pour outside because now I know that there won't be any water stains on my car!! Unbelievable!
Its use is very easy.
Instructions: (After washing your car) Put 200ml of water and then add 40ml of Polar Seal. If you have a pressure washer, put it in a foam sprayer. If you don't have a pressure washer, put it in a pre-pressure sprayer. I put it in a sprayer and it did the job perfectly. Once you pour the product all over the car (except the windows), rinse it with water. Wipe it off and wait for it to rain to see its effectiveness!!! As for the price, I didn't care at all when I saw the results!!!

Attention:
1. You don't need to use it every time you wash your car. Once a month is enough.
2. I put it in a sprayer to avoid accidentally spraying it on the windows, as would happen with a pressure washer.
3. Shake the product when you have mixed it with water (circular motion to mix it with the water).
4. Don't forget, Polar Seal is the final stage of the wash.
