Didn't expect the 18ml pot to last this long, honestly. A single application covers the base and the shade on yellow armor, which normally takes me two or three passes. The finish is smooth too, no chalky texture like some yellow paints.
One coat over a white base and my Space Marines' shoulder pads already look shaded without any extra work. The 18ml pot goes further than I expected too.
Yellow is usually a pain to get smooth, but one coat of this over white primer gave my Ork boys a solid base with natural shading in the recesses. The 18ml pot is small, though it goes further than I expected since you're not layering three colors.
