hi all i own a revell starter class airbrush and i am wondering where you can get the airbrush needles for it in different sizes?
can anybody help please

Darren, if you have the Revell's (39200) Starter Class Airbrush Complete Set (pictured below), then it does not have a needle.

yes i do but can it spray small parts etc and what is the best paint to use for it?

Darren, have a look over at Airbrushtalk, it better explains what you want and need to know about airbrushes.
