How long after painting can you wash the car?

[LillianaLee]

The car should not be washed until at least 48 hours after painting, as the hardener and paint mixture requires a full 48 hours to completely cure. Painting sequence: The painting sequence for a car starts from the top of the vehicle to the doors, then proceeds around the car body. This spraying sequence helps avoid surface overlaps and interface marks. The spraying speed should be consistent, without any skipping or missing spots. If uneven coloring occurs during painting, you can reduce the paint viscosity and then continue spraying the uneven areas. Post-painting maintenance: When washing the car, avoid doing so under direct sunlight, as dried cleaning agents can easily leave marks on the new paint. Use dedicated neutral running water for washing, and avoid using soap water with high alkalinity to prevent washing away the oils in the new paint. When taking the car to a car wash, ensure the attendants don't use wax-stripping detergents, as these can potentially damage the paint surface.
