How Long Does Paint from a 4S Shop Last?
2 Answers
The paint applied at a 4S shop can generally last for 4-5 years under normal usage. Here are some relevant details: Precautions for Car Painting: If the car has just been painted, avoid exposing the newly painted areas to water and dust. It's best not to drive out in rainy weather, as the fresh paint is still delicate and contact with rainwater can leave marks that may be unsightly and difficult to remove, even with polishing. Parking indoors overnight is the best option. Benefits of Car Painting: Prevents oxidation and corrosion of metal surfaces, and enhances the adhesion between the metal surface and the filler or intermediate and top coats. Car primer, also known as rust-proof primer, is the base coat applied directly to the surface or over the filler.
My old Passat had its door paint touched up at the 4S店, and even by the eighth year when I sold it, there was no bubbling or cracking. Their paint booth was like an operating room with a dust-free environment, using original formula color paint plus two-component clear coat, achieving a thickness of over 120 microns. However, when parked outdoors later on, it still aged faster than the original factory paint. It's advisable to avoid the rainy season for the work, not to wash the car for three days after painting, and not to wax too frequently in the first three months.
