Why do I need car wax

Wax is the primary material to prevent the oxidation of the paint of an automobile. The protective layer formed by the car wax is only enough to save the paint from oxidation and it cannot form complete protection from all damage, such as bird droppings and scratches from heavy objects. Car wax also gives your vehicle a natural shine and saves it from harsh environment.
Waxing a car helps in forming a protective layer over the car which gives it great protection. This layer helps in covering minor scratches and stone chips by making them less visible. Car wax also reduces corrosion due to water as it forms a seal on the pain through which water cannot enter. Car wax has to be reapplied regularly and is not permanent. The life of a good quality car wax is 3 to 4 months thus there is a need for reapplication every 3 months.
Before a car is waxed it is preferred to get it buffered with an electric buffer to remove minor scratches and nay irregularity in the paint, after buffering only it is advisable to wax the car which should be repeated every three months. The essentials to start waxing your car is wax, a clean soft towel and a small sponge. Also your car needs to be clean and dry before you start waxing it. Be careful as to take a non abrasive car wax so as to not damage your car. Read the directions clearly given on the package and first test it on a small area.
While using liquid car wax, first shake the bottle well, and put small amount of the wax on the sponge to apply evenly on the car. While waxing follow a top t bottom approach as it generally considered that the bottom panel of the car are the most dirty. It is advisable to apply a thin layer evenly all over the car and care should be taken that the layer is not too thick which could reduce the lustre of the car. Waxing any other part other than the painted metal part is not a good idea as it will leave a white mark all over the rubber or glass parts.
After letting the car wax be for a minute or two, buff it with a cloth which will give it a nice natural shine. Waxing the car is considered very beneficial in the long run as it helps in reducing scratches and gives the car a nice shiny lustre.
