All this being said, I have not really used any new techniques on the XIII models yet. But I have settled on the plan to do basic weathering 1) using powders and 2) light sponging. Next weekend, I intend to buy at least a pack of Vallejo pigments (Stone and cement, city). I intend to weather the lower calf and feet of the Legionaires with a light dusting of a light grey pigment to represent them defending the shattered civiti of the 500 Worlds of Ultramar. My XIII Legion are now having to forgo superficial maintenance and thus I will "chip" and "mud" where I think it is appropriate. But that is all to come.
For now, I will finish up highlights on black and apply transfers over the next week.
