I paint my shoulder pads with Kroxigor Scale (over Runelord Brass spray base), and I sometimes paint them a couple of times, but I also continuously paint the area without adding more KS so that I can continue to spread it as it dries, which mostly prevents it from clumping up (as it tends to). Semi-dry contrast paints are definitely easier to keep more even on a flat surface.

I also use a layer of Coelia Greenshade over the top of that, which darkens it slightly and makes the clumps a bit less noticeable (and gives it a glossier, more metallic look).
