What is ceramics and why do you need it? Ceramics give your car body a particularly strong, exceptional shine and a water-repellent protective coating, unlike car waxes which last a few months at most, ceramics have a lifespan starting from 1 year and the stronger versions go up to 7-8-9 years. It is easy to remove bird droppings, pitch and other environmental factors from ceramic treated surfaces. Washing the car becomes particularly easy as ceramics are hydrophobic or water repellent.
