A year or 2 ago my brother gave me his airbrush kit. He told me the needle needs replacing but doesn’t remember what size as it’s been years since he used it. It’s an Iwata HP-C Plus. Can anyone point me in the direction of a replacement needle for it? Not knowing the lingo makes it hard to work out what I need to buy.

Also, as I’m o my starting out with PLA+ on my printer, what should I buy to paint it with?

Thanks.
