The easiest way to understand this is: if the damage hasn’t penetrated past the clear coat into the original paint, it can be corrected. This includes swirl marks from improper washing, light surface scratches, stains from bird droppings and tree sap, etching from acid rain, and more. However, some bird droppings are highly acidic and can burn through the clear coat, causing permanent damage once they reach the paint layer. Protecting your vehicle and addressing contaminants quickly is essential to maintaining its flawless finish.
