How Long After Painting a Car Can You Wash It?

[LeahLynn]

In good weather, one week is sufficient, while in cloudy conditions, 15 days are recommended. Below is expanded information on precautions during the painting process: 1. Gun Adjustment: Before spraying, ensure the spray gun and related equipment are clean and in proper working condition. Check if the gun produces an ideal spray pattern. The ideal pattern should be symmetrical with evenly distributed atomized particles, clear edges, and minimal overspray beyond the pattern edges. Lower atomization pressure helps achieve correct, uniform spray patterns while reducing bounce-back and overspray. 2. Gun Handling: Maintain the spray gun perpendicular to the workpiece surface during application. The distance between the gun and surface typically ranges from 15-30cm depending on the surface angle. For wetter, darker, and thicker coats, reduce the distance; for drier, lighter, and thinner coats, increase it. 3. Gun Movement: This involves the gun's angle relative to the surface and its travel speed. Keep the gun at a right angle to the surface while moving parallel to it. Maintain a consistent speed between 30-60cm/s. Tilting the gun, arcing motions, or varying speeds will result in uneven paint thickness, potentially causing streaks or blotches.
