What nozzle size do I need for miniatures?
0.3mm is the versatile all-rounder for base coats and priming; 0.2mm suits fine detail work. Larger nozzles (0.5mm) are for terrain and big surfaces.
Do I need a compressor with a tank?
A tank smooths the airflow and reduces pulsing, giving more consistent results — worth it if you spray regularly, but tankless compressors work fine for occasional use.
How do I keep an airbrush working well?
Flush with airbrush cleaner between colours and strip-clean after each session. Most spraying problems are cleaning problems.
