How many days after 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, the spray gun and related equipment should be clean and in proper working condition. Check whether the spray gun produces the ideal spray pattern. An ideal spray pattern should be symmetrical, with evenly distributed atomized particles, clear edges, and only a minimal amount of overspray beyond the edges. Lower atomization pressure helps achieve the correct, uniform spray pattern, reducing bounce-back and overspray. 2. Holding the Gun: The correct spraying path should remain perpendicular to the workpiece surface. Depending on the angle of the surface being painted, the distance between the spray gun and the surface is generally 15~30 cm. To obtain a wetter, darker, and thicker coating, the distance can be closer; for a drier, lighter, and thinner coating, the distance can be farther. 3. Gun Movement: Gun movement includes the angle of the spray gun relative to the surface and the speed of the spray gun. The spray gun should be kept at a right angle to the surface and moved parallel. The movement speed of the spray gun is typically adjusted between 30~60 cm/s and should remain constant. If the spray gun is tilted and moved in an arc or at variable speeds, it will result in uneven paint thickness and may cause streaks and spots.
