I am already on my second liter, my first bottle lasted several months. You can apply it with a sponge or a cloth, or with a hand sponge. You leave it on for 5 minutes as the company says, but I would say 10 to make it shine and wipe it off. It gives a very strong shine, like a sparkling car. It lasts for 2 months normally, but with frequent washes, I will tell you if it is careful or with a neutral pH shampoo, it lasts 1-1.5 months. I have tried over 6 waxes and so far this is the best, especially in terms of durability. It is in liquid form, like water, not like the others that are creams or pastes. It requires a little bit... Buy it, you will see the difference

Excellent product and very easy to use. Application with a sponge, a short wait for it to dry (it becomes cloudy), and polishing with a microfiber cloth. It is easily removed and leaves the surface velvety smooth with an incredible shine. Because it is solvent-based, it removes previous waxes or sealants as well as tar residues. It has excellent hydrophobic properties. It does not stain plastics. I don't know yet about its durability, but I will come back to it. Even if the protection lasts for a month, the 1-liter bottle will last for a long time.

Edit after about 1.5 months: after rain and snow, there is sufficient protection on the sides of the car, and it still holds up on the hood and roof. Under these weather conditions and considering that the car is parked on the street, I consider the wax's durability to be absolutely satisfactory.
