Can the Paint Repair at a 4S Store Last for 8 Years?
2 Answers
The lifespan of paint repair at a 4S store is related to the quality of the paint used and the construction process. If done well, it can last for more than a decade, but if poorly handled, it may crack within a year or two. Below is a detailed introduction to automotive paint repair: 1. Overview: Automotive paint repair refers to applying a layer of paint to the car's surface to protect it. Automotive paint is typically baked-on paint. In automobile manufacturing plants, after the frame and body are welded, the next step is painting. Types include standard paint, metallic paint, and pearl paint. The process involves applying putty, sanding, and painting. 2. Composition: Automotive paint generally consists of four basic components: film-forming substances, pigments, solvents, and additives. The film-forming substance is the main component of the paint, responsible for keeping the pigment bright, ensuring durability, and adhering to the surface. Pigments are one of the two non-volatile substances in paint. Solvents are the volatile components in paint.
Having worked in the automotive repair industry for several years, I believe whether a 4S shop's paint job can last 8 years depends on the specific circumstances. They typically use OEM-grade paint materials and spray gun equipment, which are relatively stable in quality. There are quite a few influencing factors: whether the daily parking environment involves a lot of sun exposure, the acidity level in rainwater, and the frequency of car washes—if the car is mostly parked in a garage and regularly waxed for protection, the paint's resistance to aging is stronger, and it can hold up for 8 years without major issues. However, if the car is often left outdoors exposed to harsh sunlight or suffers frequent scratches, the paint may start bubbling or fading within just three to four years. I recommend car owners conduct regular simple inspections and address minor scratches promptly to avoid bigger, more costly problems later.
