Usage Methods and Skills of RDSWA Airbrush

I. Basic Usage Methods

1. Preparation: Assemble the airbrush, check the air circuit for smoothness, pour the paint diluted to an appropriate concentration into the cup (usually the ratio of paint to thinner is 1:1~1:2, adjusted according to the paint type), and adjust the air compressor pressure to 0.1~0.3MPa.
2. Debugging and Test Spraying: Keep 5~10cm away from the waste cardboard, press the trigger (air first, then paint), test spray a uniform fan-shaped mist, adjust the paint output and air pressure to ensure no dripping or intermittent spraying.
3. Formal Spraying: Keep the airbrush perpendicular to the model surface, move at a constant speed (2~3cm/s), overlap the spraying area by 1/3 to avoid local accumulation; spray the primer first, then the topcoat, spray each layer thinly, and wait 5~10 minutes for it to dry before spraying the next layer.

II. Core Skills

1. Detail Control: When drawing fine lines (such as model lines), move the airbrush closer to 3~5cm, reduce the paint output and air pressure, and press the trigger gently; for large-area spraying, pull the distance to 10~15cm, increase the paint output, and move at a constant speed.
2. Effect Creation: To simulate gradient/shadow, gradually change the airbrush distance or moving speed to make the paint transition naturally; to simulate wear/rust, cover with masking tape, spray dark paint locally thinly, then spray light paint lightly for transition.
3. Maintenance Skills: Clean the cup and needle with a special solvent immediately after spraying to avoid paint drying and clogging; regularly check the wear of the needle and replace it in time to ensure the atomization effect.

III. Notes

• Avoid pressing the trigger continuously for a long time to prevent paint accumulation and airbrush overheating.
• Keep the spraying environment ventilated to avoid inhaling paint mist and prevent dust from adhering to the model surface.
