Well, the short answer to this question is probably. For a long time now, waxing has been known to make cars extra shiny. Today, the same theory still applies with modern paint jobs. Wax formulations have also improved over the years. In the past, the paint used to be just painted, and a new car would just get a coat of primer and coats of color lacquer, and it was done. Therefore, wax did not only give car paint a good gloss; it was the only defense against scratches.
By the beginning of 1980, a lot of manufacturers began adding a layer of the clear coat; that works by sealing the paint and adding a shine to the car. That wasn’t the only purpose, as the clear coat was meant to take all the environmental abuse from ultraviolet light, Ozone, salt, Dirt , Rain, and bird poop that build up tiny scratches and oxidation on the clear coats surface.
Therefore as the paint job ages, it begins to form some sort of haze, and the shine subsides leaving the car with a dull look. If you are not particular about how your car looks, you can be lazy and never wax it; you can just wash the car since it leaves the car looking reasonably nice. However, you need to know that waxing your car usually leaves a sacrificial layer on top of the clear coat, so that when dirt is removed from the car, you are not directly rubbing the paint.
However, nowadays things have changed significantly, and you don’t need to spend all your Sunday afternoons waxing your car. This is because the new synthetic formulas are simpler to apply and offer an even longer lasting protection on your car. You also do not need to wax that often, even if you have an obsession with your paint. It advisable to wax your car twice a year, once before springtime and once during spring.
