Doing research on the internet, I saw many foreign sites for last year, this particular product to have the best reviews and so I decided to try it. Indeed, its results are amazing. No effort in applying it on the car and wiping it off afterwards.
Its effect lasts for about 5 months. Water glides on the surfaces and doesn't stick. Superficial scratches and any marks from water or dirt disappear. To finish the bottle, I did the whole car 4 times, so if you consider that you will do this job every 5 months, then you understand how long it will last, so it's worth its money.
