Hello, this is the continuation of the "Why does my car get scratched" post. There is no AI assistance in my writing * : refers to a technical matter that varies depending on the situation. How Do Dullness and Scratches Damage Your Car? Dullness isn't caused only by scratches that build up over time. Harmful contaminants like tree sap, tar, iron particles and exhaust soot stick to the paint surface. Every day they stay on the surface, they work their way under the clear coat and disrupt the paint's chemistry. The Cycle of Harder Cleaning and More Scratches: A surface that has lost its smoothness traps dirt and water. Washing your car becomes harder, and even drying it after a wash turns into a chore. Loss of Resale Value: When selling a used car, the first thing that catches the eye is the condition of the paint. A neglected, dull, scratch-covered body directly lowers your car's market value. In short; scratches and dullness are a result — the real danger is the paint layer being left defenseless. Can Scratches Be Removed? While light defects can be removed*, defects that go deep into the clear coat are scratches that are risky to remove. Scratches that reach beneath the clear coat can't be removed by polishing*, and are instead touched up to hide them. When doing these procedures, the surface absolutely must be analyzed and worked on systematically. What should I do to protect my car? You should wash it correctly. As support, you should use paint protection methods. The most effective of these is PPF. After that comes ceramic coating and other waxes. I could open separate topics one by one for each paint protection method, but to give a quick rundown: PPF cuts off the paint's contact with the outside environment with a physical film, preventing it from getting damaged. A quality PPF self-heals light scratches, and thanks to the surface-tension top layer it creates, it makes washing easier. Ceramic coating reduces friction by creating surface tension. This way you scratch your car less while washing and drying, it delays getting dirty and makes washing easier.
