Yes!! Once the question about weathering armor is asked, it's all over. The turn to the dark side is complete.
I am no expert on weathering, but I like Bish's response due to the control over the effect that gives.
I used an acrylic wash as a fixer, which worked well where I wanted the dust to accumulate, but not so well for a lighter covering. I got actual brush strokes on the model when I went for a lighter coating, which I did not want.
Try using a little dry on a brush to see what effect you get. I found that not using anything but the pigment gave a subtle, but noticeable dusty effect.
Happy to hear you are enjoying armor.
