Getting weathering powders to stick

Wanted to know what you guy’s use to get your weathering to stick to your models?

I got some mig pigments and they work great but when I go to dullcoat the model it seems to wash most of the weathering off. What do you use to seal the model flat and also seal the powders? TIA

LOL…I just started using MiG pigs recently myself and ran up against the saame problem. I have also read MiG’s book and pamphlets on how to use his pigments. And the answer is, “you can’t make them stick” (assuming you are using them to replicate dry dust)…if you spray laquer on it it will either blow them off or “melt the pigs” down so that tghey are no longer dust…MiG even admits such in his book…he recommends minimal handling of model after using them, and if you do mar the model/dio, simply touch up with fresh pigment…see my dio “Defense of Aachen” for more visuals on the pigs used as dust…I had to reapply the dust after spraying Dullcoat on the first application…

mig pigments can be fixed by using mig thinner or an equivilent.it makes them fairly stable,but as you said you can’t clear coat them.

That’s true, but they lose their “dusty” effect to a certain degree if you try to affix them w/ anything…the MiG thinner, etc. gives them more of a dried mud look than anything else…

You want to clear coat your models before you apply the pigments. And typically you want to obviously add them to a flat finish, as they will stick to the grain of the paint. if you want to fix them in place a little better, what you can do is presoak the part of the vehicle to be covered in thinner (I use turpentine) and then apply the pigments, but be careful to apply enough to get an even coating, but no clumping, as it will look like mud. An additional step, that I like to do, is actually MIX the pigments with the turpentine in a dish, and create a paint. Apply this paint to whatever parts you wish. When it is fully dry, it will be a flat finish. At that point, you can use an old toothbrush or other stiff brush to remove most of the pigment, and leave it in the crevices and impart a generally dusty appearance.
