Modern conditions place a heavy burden on the life of a paint finish on any road vehicle. The influence of acid rain, traffic grime, road salt, bird-lime (bird droppings) ultra-violet rays from sunlight, dampness and moisture, changes in temperature, industrial gases, tree sap etc. all work to take a toll on the condition of the vehicle's paintwork. In addition, the use of detergents when washing cars, and the physical abrasive actions of the washing itself have a detrimental effect on the paint finish.
