Which size Airbrush needle to use.

I purchased a Paasche ‘H’ airbrush. It comes with 3 needle sizes, 1,3 and 5. Can someone please tell me which needle size to use for Tamiya Arcylic paints. Thanks.

You can use all three with Tamiya or for that matter just about any other hobby piant.

For base coats I’ll use #3, fine camo lines #1, and rarely use #5.

As a rule a medium tip/needle is what you need for general purpose job.
