Can a car be repainted with just a clear coat?

[McCora]

It is possible to repaint a car with just a clear coat, but it should be done at a professional auto repair shop or a 4S dealership. A car's paint surface consists of four layers, from the inside out: the electrocoat layer, the primer layer, the base coat (color layer), and the clear coat layer. After the entire car body is assembled, robots immerse the body in an electrocoating bath, forming an electrocoat layer on the surface, which serves as rust protection. Minor scratches typically remain on the clear coat layer and can be removed through simple polishing. However, frequent polishing is not recommended, as it reduces the thickness of the clear coat, leading to a loss of gloss over time. If there are minor scratches on the clear coat, they can generally be ignored. However, if the scratches penetrate to the base coat, a full repaint is required for repair.
