What are the yellow spots on white car paint?
3 Answers
Small yellow spots on the car's paint surface are iron particles, which turn yellow after rusting. Every car has iron particles, but they are more noticeable on white cars. Here is some extended information about car paint: 1. To remove these yellow spots, a specialized iron particle remover is required. It is recommended that car owners visit a professional auto detailing shop for iron particle removal. 2. A car's paint consists of four layers: the electrocoat layer, the primer layer, the basecoat layer, and the clearcoat layer. 3. The clearcoat layer is essentially a transparent layer of paint that protects the basecoat layer and enhances the gloss of the car's paint surface. Everyday stains and scratches typically remain on the clearcoat layer. 4. Scratches on the clearcoat layer can be removed through simple polishing. However, frequent polishing is not recommended as it reduces the thickness of the clearcoat layer, which over time can cause the car's paint surface to lose its shine.
I usually drive a white car, and finding yellow spots is quite common. They are typically caused by the oxidation of the car paint after prolonged exposure to sunlight, as UV rays can turn the paint yellow. Additionally, bird droppings or tree sap that aren’t cleaned promptly can dry and turn into yellow spots. Environmental contaminants like acidic substances in rainwater can also erode the paint. For treatment, I first use car cleaner and a soft cloth to gently wipe the spots, followed by waxing for protection. To prevent this, park away from direct sunlight or under trees, and waxing the car monthly in summer can slow down aging, avoiding larger yellow patches that are harder to deal with.
Dealing with car paint issues is my habit. When you see yellow spots on a white car, don't panic. Most likely, they're caused by contaminants like bird droppings or small rust particles. I often use a slightly damp soft cloth dipped in professional cleaner to gently test a small area. If that doesn't work, it might be internal oxidation, requiring a trip to the car wash for polishing. For prevention, wash your car frequently, especially after rain or parking under trees. Applying car wax or coating forms a protective layer - a DIY solution costing just tens of yuan that saves money and prevents future damage. Otherwise, accumulated damage to the paint surface will cost much more to repair later.
