Do polymer paintwork protectants really work?
Using polymer sealants will help a car paint last longer by providing a protective layer over the paint, preventing damage by various substances such as water and acid rain.
Corrosion is actually the process by which the surface of a substance (such as metal) undergoes a chemical reaction with elements in its surrounding. One example, is the process of oxidation - this occurs when metal is placed in the presence of water and oxygen. This is how rust forms. Painting is one of the most common methods used to prevent rust from occurring. However paint itself is vulnerable to damage by industrial and naturally-produced chemicals and therefore additional coatings such as wax or polymer sealants are applied over the paint to protect it. This prevents the paintwork itself from corroding.
