Does Painting Require Removing the Original Paint?

[DeXavier]

Painting does require removing the original paint because repainting increases the thickness of the paint film, making the painted area higher than the original surface. Therefore, the original paint must be cleaned off before applying new paint; otherwise, the paint surface will become uneven and noticeably raised. Precautions for full-body painting: 1. Pay attention to color differences; 2. Take protective measures; 3. Monitor the spray gun pressure and working environment during painting; 4. Control the baking time. The general painting process involves: first performing bodywork, grinding down the original paint and base layer of the area to be painted to a level two coats thinner than the standard paint surface, then applying putty, mixing paint, spraying, baking in a paint booth, and finally air-drying for over ten hours.
