How Long After Sheet Metal Painting Can You Wash the Car?

In good weather, one week is sufficient; in cloudy weather, 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 normal working condition. Check if the gun produces an ideal spray pattern. An ideal pattern should be symmetrical, with evenly distributed atomization and clear edges, with minimal overspray outside the pattern edges. Lower atomization pressure helps achieve correct, uniform spray patterns, reducing bounce and overspray. 2. Gun Handling: Maintain the spray gun perpendicular to the workpiece surface. The distance between the gun and the surface is typically 15~30cm, depending on the angle of the surface. For a wetter, darker, and thicker coat, reduce the distance; for a drier, lighter, and thinner coat, increase the distance. 3. Gun Movement: This includes the angle of the gun to the surface and its speed. Keep the gun at a right angle to the surface and move it parallel at a constant speed of 30~60cm/s. Tilting the gun or moving it in arcs or at variable speeds will result in uneven paint thickness, leading to streaks and blotches.
