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

"A car can be coated with a single layer of clear paint, but it must be done at a professional auto repair shop or 4S store. Pre-treatment before car painting: The entire body is immersed in an electrophoretic pool, forming an electrophoretic layer on the surface of the car body. Requirements for car paint: It must have good mechanical properties, excellent fullness, high gloss, as well as strong adhesion, high hardness, and good scratch resistance."
As someone who frequently handles paint repairs, I believe applying a single layer of clear coat is a feasible solution, especially for minor surface damage. For instance, when there are only slight scratches on the clear coat of doors or bumpers but the base color remains intact, simply respraying a new clear coat can restore gloss and protection. The process involves thoroughly cleaning the damaged area, lightly sanding it smooth with fine-grit sandpaper, removing dust, then applying one or two coats of clear coat, followed by polishing after drying. The key is selecting a product compatible with the original paint to avoid color mismatch or gloss inconsistency—professional tools can further enhance the results. However, it's important to note that if the damage reaches the base coat or shows rust, merely applying clear coat is a temporary fix that may peel or yellow over time, so always assess the depth of damage first. Small touch-ups save time and money, but for extensive issues, a full inspection at a repair shop is more reliable to avoid repeated fixes that could worsen the problem.
