How do you thin acrylic paints to airbrush miniatures? As a best practice, you should thin your model paints to the proper viscosity for your airbrush. The proper viscosity for airbrushing depends on the air pressure, the resolution, and the airbrush nozzle size.
For simplicity, of course, you could buy “airbrush-ready model paints”. But, these can be costly and may still need thinning for best results with your airbrush setup.
I always recommend to anyone with an airbrush to learn how to thin acrylic paints for painting miniatures.
