How Long Can Bodywork and Paint Last?
2 Answers
Bodywork and paint can last for five years. Here are the specific details about bodywork and paint: Depreciation range: The price difference between repainting and retaining the original car paint is between 10-15%. If the paint job is not done well, the difference will be even higher. If the bodywork and paint are due to an accident, the depreciation will be even greater. Painting any part of the car surface will cause depreciation. Function of paint: The paint on the car surface belongs to metal baking paint. After baking paint on the steel surface, the surface paint can resist acid and alkali, prolonging the life of the car's steel components. The working principle is based on optics and mechanics, using the lever principle to gradually restore dents of different depths to their original factory condition.
Last time I worked on a decade-old Accord in the workshop, and the panel painting result was still decent after disassembly. The key to this kind of job lies in three points: first, whether the mechanic thoroughly removed rust from the steel plate when applying filler; second, whether the temperature control in the paint booth is stable enough; and third, how many layers of topcoat were applied. The factory standard requires at least primer + basecoat + two-component clearcoat. If shortcuts are taken at roadside shops, bubbles will appear after two years under the sun. With imported clearcoat and proper baking, it can easily last five or six years. However, extra caution is needed in coastal areas—salt mist corrodes steel plate joints particularly fast, so it's recommended to wax and seal edges and corners quarterly.
