How Often Should You Wax Your Car?
Regularly waxing a car is essential because it helps preserve the clear coat over a vehicle's paint. That clear coat is the layer that protects the paint from corrosive elements, including snow, rain, street salt, ultraviolet rays, bird droppings, and tree sap, among other contaminants. The clear coat is also what gives a vehicle its shine.
When the clear coat wears away, the paint becomes susceptible to fading, discoloration, and eventually, rust. In other words, applying wax is a necessary component of keeping the exterior of a car in the best possible condition and retaining a vehicle's resale value.
As a general note, always wash a vehicle before waxing it. Doing this removes surface dirt, debris, and grease so that you can apply the wax cleanly and evenly over the vehicle's clear coat. Not washing a car first can cause the wax application process to grind dirt and other particles into the paintwork.
