1. Reasons why car spray paint bleeds
Spray paint sagging (also known as "bleeding") is usually caused by:
| reason | illustrate |
|---|---|
| Spray paint too thick | Spraying too much paint at once can cause the paint to run quickly instead of drying quickly. |
| Improper diluent ratio | Too much thinner can reduce paint viscosity and increase the risk of flow. |
| Spray gun is too close | The distance between the spray gun and the car body is too close, causing local paint accumulation. |
| Ambient humidity is too high | In a humid environment, paint dries slowly and tends to sag. |
2. How to deal with runny car spray paint

| step | Operating Instructions |

| 3. Clean the surface | Use a clean cloth or compressed air to remove sanding dust. |
| 4. Repaint | Spray a thin layer on the sanded area, taking care to control the distance of the spray gun and the amount of paint. |
3. How to prevent spray paint from sagging
To avoid spray paint sagging, you can take the following precautions:
| measure | illustrate |
|---|---|
| Control paint thickness | Use the method of "thin coating and multiple layers" to avoid spraying too thickly at one time. |
| Adjust dilution ratio | Adjust the thinner ratio according to the paint instructions to ensure the right viscosity. |
| Maintain proper spray gun distance | Keep a distance of 15-20 cm between the spray gun and the car body and move evenly. |
| Choose the right environment | Carry out spray painting operations in an environment with suitable temperature and low humidity. |
