In this blog post, UPPF divides fading and loss of light into the following situations according to the different symptoms of car paint protection film fading and loss of light.
1. Fading and loss of light caused by harmful substances
Use a magnifying glass to observe the paint film of the car body. When there are holes of irregular size on the surface of the car paint protection film, the cause of this kind of fading and loss of light is mostly caused by harmful substances.
The paint film is exposed to the outside for a long time without any protective measures, causing various harmful substances to adhere to the surface of the paint film and gradually penetrate, forming voids of irregular size that are invisible to the naked eye, and these voids are easy to hide. Dirt, so it will inevitably affect the permeability of the paint surface, just like brushing a thin layer of paint on transparent glass, the paint surface will lose its luster, and the color of the base paint layer will also change. Covered by this layer of oxide, it loses its original bright color.
2. Fading and loss of light caused by oxidation
Use a magnifying glass to observe the paint film of the car body. When there are no obvious scratches and few spots on the surface of the paint film, the cause of such fading and loss of light is mostly caused by oxidation-reduction reactions.
3. Loss of light caused by scratches
When there are many fine scratches distributed on the paint film without damaging the primer layer, especially when it is more obvious under strong light irradiation, this kind of light loss is caused by shallow scratches.
4. Fading and loss of light caused by lens effect
Use a magnifying glass to carefully observe the cleaned paint film. There are many spots on the paint film. These spots are actually small holes caused by burning. The fading and loss of light are caused by the lens effect.
