When your car was painted it was covered with a clear coat to protect the paint. Waxing your vehicle on a regular basis will help protect the paint. Show stopper wax will give it that deep showroom shine that people love.
Not only will waxing help reflect the sun but it will also leave the surface smooth and slippery. This will help keep dirt and grime form sticking to the surface and scratching your vehicle.
You should wax your car 2 to 3 times a year as a regular service just like changing your oil or rotating the tires.
