Very easy to use. Even though I don't have a polisher and did the car by hand. Don't worry if it gets on plastic. It doesn't leave marks. Even though I applied it on a sunny day, I had no problem. I just left it on for a little less (about three minutes) and then wiped it off with the microfiber cloth from the kit. It's very convenient as you don't need to buy the tools separately. For a large sedan or SUV you might need another sponge. I recommend it.

Wonderful in everything: ease of application, results, longevity. I use it alternately with the ultimate quick wax spray. I will buy it regularly. *****

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.
