What is the method for visually identifying a car's original paint?

Determine whether repainting has been done by observing the contrast of light and shadow reflected on the car body. Poor-quality repainting will result in noticeable color differences that can be detected visually. Repainted areas may feel less smooth, and unevenness on the car body can also be detected. Check for any residual paint and color differences compared to the car's original paint.
I've repaired quite a few cars before, and identifying original paintwork can be done just by eye. First, find a well-lit spot, preferably under sunlight, to check if the body's gloss is uniform. Original factory paint reflects light smoothly, without any discoloration or spots. Then run your fingers lightly over the surface—it should feel silky smooth. If it feels rough or has tiny granules, it's likely repainted with orange peel texture. Pay close attention to details like door edges and hood seams—original paint will be mirror-flat, while repainted areas may show thicker layers, paint runs, or slight color variations. Angles matter too; compare side and frontal views—consistent color means it's reliable. Why does this work? Original paint is high-temperature baked at the factory with even thickness, whereas repainting is often done at room temperature, making flaws obvious. When helping friends pick used cars, I use this method to avoid accident-repaired vehicles.
I've been into cars for many years and love studying the details of car paint. Identifying original factory paint isn't difficult: lighting is key. Check the reflection consistency under sunlight or artificial light - genuine original paint shows continuous halos without breaks. Focus on corners like mirror bases or door hinges; repainted areas often appear darker or have rough edges, while factory paint is crisp and clean. Feel the surface texture - it should be smooth as glass; any bumps or gritty sensations indicate repainting. Observe color changes in shadows - original paint shows minimal color shift, while repainted areas appear inconsistent under different lighting. During routine maintenance, pay attention as repainted cars tend to fade faster, while original paint lasts longer. Last time I helped inspect a car, I noticed thicker paint on the trunk edge - it turned out the vehicle had been in an accident. This method really helps avoid pitfalls.
