In addition to countless environmental factors, catalytic emissions from the cars around you are depositing hydrochloric or sulfuric acid particles on your car’s upper surfaces. All of these contaminants take a toll on your car’s paint if the finish is not properly maintained. A wax provides what we can call a sacrificial barrier against these elements. It takes the strain so your paint does not have to. Thus a thin layer of wax cannot last forever and regular applications will ensure your car remains protected.
