Airbrush tips

[Airbrush Intraining]

What really makes an expensive airbrush much better than a cheap one if they are both dual action?

ALso what are the factors involved when the airbrush is not spraying anything at all and the needle seems to be stuck?

The name brand airbrushes have high quality control standards and a name to uphold while the no name or rip offs have zero to very little QC and are usually using cheap components.  Good luck getting some help from them.

Needle bushings are probably too tight if the needle isn't moving on a new brush.  If it's a used brush it might be bushings but more likely dried paint.
