I recently have gotten some weathering powders for my minis and wanted to share how I use them. They can add a lot to your mini and you don't need much to try them out. There are many different brands of pigments on the market, but they all can be used the same way. All you need are the pigments and something to fix them with.
I use the Vallejo type pigments, because I'm a fan of their brand in general and my FLGS stocks almost all of their product line.
I've tried two very different approaches thus far. One where I apply the pigment dry and fix them afterward and one where I apply the pigment wet.
1. Apply dry and fix wet
For this method you just take a brush and apply the dry pigment generously to the areas on your mini you want to weather. When you're satisfied, you'll need something to fix the pigment with, or otherwise all your work will be for naught. I use 96% proof Isopropanol alcohol for this. Just take a brush and dip it into the alcohol and touch it to the weathered parts. The capillary action will draw the alcohol right onto your fig and the pigments will set in all the crevices. The moisture will then evaporate - but you still will need something to protect the weathering from future wear. For this, is use one or two coats of matte varnish, which will secure it and take the shine of, adding to the overall effect.
BEWARE: Before using alcohol, coat your mini with varnish, as the alcohol can damage your paintjob. Just look at the foot of my Warjack - on the screw in the middle the alcohol took some of the silver paint right off.

2. Apply wet
For this, I used Vallejos Pigment Glaze and some pigment to create a wash. I applied this liberally to the areas I wanted to weather and just waited for it to dry. Afterwards, I sealed it with varnish to keep the pigment in place.

And that's all there's to it. As always, enjoy and have fun!
