AIM Rusty Brown weathering powder is a very nice dark brown rust color. I have sets of powders from Bar Mills and Bragdon, and there is no dark brown rust color like this in either set. It works as well as the other brands of powders that I've used. The other great thing is that they have many colors and you can buy each one separately. There's enough in each $5.00 container to last the average modeler 3 lifetimes,so if you spit it with five friends, you could each have plenty for only a buck. The only thing that would be better is if they sold separate containers half this size for half the cost.
