One misconception about ceramic coatings is that you need multiple bottles to cover your car.
In fact, a bottle of ceramic coating that contains around 60ml of the solution can be used on more than one car.
This is a great option if you have more than one car that requires a ceramic coating. Smaller containers are also available if you prefer a solution that will only cover your car.
While this is the general rule for the average car, take note that you should take a few factors into account. The size of your car plays a major role in how much ceramic coating you will need. Larger cars and trucks would, of course, need somewhat more of the solution.
