I use Tamiya Weathering Powders set too. I find it to be very effective. Little expensive but worth it. You could apply it on uniform, equipment, and even rifles.Instead of all the hassle with pastels you should use Tamiya Weathering Powders instead. You won't have to hassle with shaving a pastel stick, and they are easy to use. Also, you can use Testors DulCote to hold the powders on and take the shine of of anything that you want to be flat.
