    Strange question. Can you airbrush Mig pigments? I was thinking of mixing them with white spirit, then misting them on. I was thinking that it would be governed by the nozzle diameter.

    I never tried, but i think it is impossible. The nozzle of the AB would get closed trough the fine particles of the pigments.
    But i could be wrong.

    I've see this same question asked on armour forums, and all signs point to a very bad, messy situation...I wish I could find the posts!

    Carl, this was asked about on CMON a short while ago (thread here).

    Since this is supposed to be done by some people technically it is feasible apparently, but no idea of what kind of AB or spraygun is being used - in theory it might work only through a nozzle much wider than on any regular airbrush.

    Anyway, are you looking for a method to get the pigment on in a fine, even layer, over larger areas? If so, dusting on with a big soft brush not sufficient?

    Guys I have ab pigments on models before and it works fine
    Low pressure and build thin layers is key build it up as each layer dries

    Hi Carl, I did this a while back but used a 'plant mister' that you use for watering plants by spraying the leaves. They can be got almost anywhere for a couple of quid mate.

    Cheers

    Thanks again for the input. Einion That's the way I normally do it. I don't trust Testors to fix them in place, as I've had problems with them drying shiny.
    Thanks again,
    Carl.

    Welcome Carl. If you want to fix pigment dusts in place with an overspray, thinned acrylic medium would work fine.

    You should be able to thin heavily (like more than 10:1 water to medium) and still get the desired result - I've used this in the past to make water-soluble paint insoluble so that it could be painted over so the same thing should work for pigment dusts.

    Plus it's very cheap and easy to do, very fast-drying (can recoat in just a minute or two) and way safer to spray indoors than anything solvent-borne.

    Can I check some details:
    any problems with getting the dry powder to disperse properly;
    was this in water only;
    which airbrush and nozzle?

    The pigment was sprayed out of a .05 nozzle and when the dust is mixed with water it tints like a wash being sprayed on/ the airbrush is a grex tritium ,hth Dave

    Thanks again everyone. Went for the soft brush option in the end.
