1. Shake the can well for at least 3 minutes after hearing the ball.
2. For the first use, spray into the air for 3-4 seconds with the black valve to remove any concentrated paint from the internal tube.
3. Choose a valve according to the application you desire.
4. Test the spray on a test surface first.
5. Spray the object you want from a relatively close distance, 5-10cm with the black valve or 1-5cm with the gray valve.
6. During spraying, move the can steadily parallel to the surface being sprayed.
7. Shake the can regularly. After finishing your work, spray upside down until clean gas comes out to clean the valve.
8. It is recommended to clean the valve with a solvent (nitro or acetone) to avoid clogging.
