Will MIG Pigments jam up my airbrush............BTW......it is a basic HUSKY airbrush nothing fancy.......all I want to know is should I attempt it or not

not if thinned properly, but then you would end up with just paint, it would IMO ruin the effect of the pigments.

There was an article recently in Scale Modeller, I beleive, that talked just about this, and that it is doable. So I thought I would try.

I have used Vallejo Pigments in my Paasche, with the larger needle and tip, I thinned with Testor Acrylic Thinner and used very low pressure. Depending on how thin or "thick" you mix it, you can get different affects, from splattered mud to dust.

Greetings,

Kevin, do you have any pictures of your models after spraying the pigments? I posted this question some time ago and was told it couldn't be done. If you did it successfully, I would sure like to know how it turned out.

I dont know about MIG pigment, but here's a video of ModelMakerZ pigment and fixative being used with an airbrush

Interesting question. So I just mixed some Sennelier raw umber inorganic pigment (ie: comes from some kind of mineral instead of a lab)into acrylic thinner and let fly. Used a Paasche VLS with a .66mm nozzle. Worked very well I'd say. Alcohol (major ingredient of acrylic thinner) works like MIG pigment fixer: I'd guess mineral spirits for their "thinner for washes" and that would have left the pigments loose after drying. Not a hint of a clog. Because I stood off a distance a sprayed wide it has the kind of effect you'd get with highly thinned Tamiya paint (like Buff) that a lot of modelers use for a final dusting. The effect is a kind of general dirtiness - indistinct because there's little pigment used. It's better than paint I'd say because pigment looks more like dirt than paint does. I like it and will try it again on my next tank.
I think something heavier would be better done by applying the pigment on and then the thinner or put the thinner on an drop the pigment on top of it. Mud would be different: there you'd want to load a paint brush up and blow air through it for a nice splatter. (Note, I used Sennelier from the art store. This is pigment sold to artists that make their own oil paints and there is nothing in the modeling world as fine. It's also cheaper by volume. But it's the same stuff as MIG etc and can't see why MIG wouldn't work just as well. If it did clog, I'd think pigments would be easy to clean out. I think it's the emulsions you find in paint to keep it together that causes the nightmare clog. As long as the pigment cant fit through the nozzle it blows right out.)
