It will depend on the kind of paint you use and the way you apply it, paints with fast drying time (like Tamiya enamel or acrylics) when applied through airbrush, dry so fast that don't allow dust particles to stick to them, but some colors when applied with brush don’t dry as fast, so it gives time to dust to stick.

When it comes to body paint, since wet coats are normally applied, some dust particles normally find their way to the surfaces, but then, some sanding will get rid of them

Also, try to paint in rooms with no dust around or people coming by; any movement around your working area will create air flows that carry dust all around.

I personally wouldn’t recommend air tight plastic containers they don’t allow the paint to cure correctly since the paint fumes won’t dissipate easily.

Hope this helps.
