Can a car be coated with just a layer of clear paint?

It is possible to apply just a layer of clear paint to a car, but this should be done at a professional auto repair shop or a 4S dealership. A car's paint consists of four layers, from the inside out: the electrocoat layer, the primer layer, the basecoat layer, and the clearcoat layer. Pre-treatment before car painting: After the entire car body is assembled, robots immerse the body in an electrocoat bath, forming an electrocoat layer on the surface. This layer serves to prevent rust. Once the electrocoat layer is formed, robots then apply the primer layer, which also functions as rust protection and enhances adhesion for the next layer of paint. Requirements for car paint: Car paint differs from other types of paint. Given the high cost of cars and their exposure to varying seasonal conditions throughout the year, the performance requirements for car paint are extremely high. Car paint must not only have excellent mechanical properties, fullness, and high gloss but also strong adhesion, high hardness, and scratch resistance. Additionally, it must possess outstanding weather resistance, abrasion resistance, gloss retention, and excellent resistance to gasoline, alcohol, acids, alkalis, and salt spray.
I've dealt with minor scratches myself before, and applying a single layer of clear coat is feasible, saving a lot of money and time. First, wash the car and dry the scratched area, then apply a thin layer with a small brush or clear coat pen—don't use too much to avoid buildup. Once dry, lightly sand and polish to blend the new and old paint. If done properly, the results can be quite good. However, I've tried this a few times and found that if the base paint is damaged or dust gets in, it can bubble or peel. I recommend only doing this for shallow scratches, like those from door handle friction; for deeper or larger areas, it's better to go to a professional shop for a full repaint. Regular maintenance like this can extend the life of your car's paint. Beginners should start with inconspicuous areas to avoid making things worse. Remember, cleanliness is key—keep your tools clean and dust-free. In short, applying a single layer of clear coat is a practical trick, but don't expect it to be permanently perfect.
