1, the car shape is more critical, and the car surface looks uneven, which greatly affects the appearance. When plastic repair, carefully observe whether the plastic parts are flat or not.

2. The second step of painting is plastering putty to see if it is smooth and uneven. If so, let it be reworked.

3. When painting, there should be a suitable place, usually a closed painting room, so that the quality of painting can be guaranteed. After painting, let the car dry fully. It is recommended to choose a higher temperature time when painting.

4. The correct spraying trajectory is perpendicular to the workpiece surface. When spraying, according to the angle of the coated surface, the distance between the spray gun and the sprayed surface is generally 15~30cm. In order to obtain a wetter, darker and thicker coating, the distance can be closer; In order to obtain a drier, lighter and thinner coating, the distance can be longer.
