Didn't think I'd care about pigment count until I saw how little I needed to get solid coverage on power armor. The finish dries properly matte, which matters when you're trying to keep that steel look from going glossy under a lamp.
One coat over a black primer and my Grey Knights terminators already look tabletop ready, no chalky patches or streaks. The matt finish is smooth enough that a quick wash settles in the recesses instead of beading up.
The pigment density on this stuff is no joke, two thin layers over a white undercoat gave me a rock-solid grey that didn't obscure any of the fine detail on the shoulder pads. Finish dries properly matte too, no chalky look like I've had with cheaper basecoats.
