Airbrush & zero paints

Hi there,
I am using zero paints with airbrush that has a 0,3mm needle. Do you, other fellow modellers use similar needle thickness, or use 0,5mm ones? Which one suits you best?
thanks
Alex

Hi Alex,

For primer and clear coat i use 0.5mm needle and nozzle. For basecoat. A 0.35mm needle and nozzle. Work great. I think you can use a 0.3mm needle and nozzle for basecoat without issues, but i would recommend a 0.5mm needle and nozzle for clear and primer.

Best regards,
Lesley

Also, I thin the paint by 1:1 ration using Zero Paints thinner and I still get a feel like "coarse sanding paper" look on my model.
The pressure is ok, but I cannot get what is wrong anyway. Do I have to spray between time-intervals? and how long these would be?

You don't to thin the paint. It's prethinned. I always spray with 15 to 20 psi presure. Works great.

I don't know the thickness of my needle.
I Just adjusted the pressure untill I was satisfied with the result.
Zero-paint is perfect for airbrushing.

I don't thin the paint. Somtime the primer needs a litle thinning but ot much. I use a 0.3 needle and a 0.4 they both work fine. I spray with 42 PSI or 3 Bar.

When you say "coarse sanding paper" are you talking about the base coat before clear has been applied? If you are then it can have some texture, but I would never describe it as "coarse" As your using a smaller nozzle size it may be advisory to add more thinner and use a touch more air pressure. Don't go too high with the pressure though. If that helps great if not, try a reduction in pressure but still with the extra thinner and see how that goes. I use a 0.5mm nozzle with extra thinner and 25-30 psi at the airbrush and it always sprays well, nice and smooth. Different airbrushes may react differently so experiment a little. The paint needs to be thin, like milk consistency usually works best.

please note that all base colors are matte, so if you want them to be perfectly smooth and shiny you need to clearcoat them.

I use a 0.3 nozzle and it works perfect for me from scales 1/43 to 1/12. I usually thin all paints with zero thinner altough they are "prethinned". For clearcoats I thin my paint around 50/50 to get a nearly perfect smooth finish, but even then I still sand everything and polish to a high gloss finish.

I use an Iwata Hp-c plus which is 0.3mm. Work perfect, no need to thin. Metalic paint sometime clog, but it's rare and easy to fix.

I now have a new iwata hp-m2 (single action 0.4mm) for those kind of paint, but still didn't try it with zero paint.
