Those wishing to reduce the incidence of damage associated with gas and oil spills, adverse weather conditions and oxidation as well as the normal daily wear and tear that parking lots and driveways often experience may wish to consider seal coating. It is a long known fact that adverse weather conditions over time tend to loosen up the top layer of asphalt resulting in eventual erosion  As moisture penetrates asphalt it will eventually break up the asphalt resulting in cracks, and pothole damage.
