My last paint pot of the old Flesh Wash is currently down to 3/4s. Also, I have one Chestnut, Brown, Black, Yellow, and Magenta ink remaining, too.
Then I have some of the washes they provided after that ... 1 each of Thraka Green, Asurman Blue, and Leviathan Purple, 1 1/4 of Gryphonne Sepia, 1 3/4 Baal Red, and 2 1/2 of Badab Black. I've used Agrax Earthshade, and actually have 1 3/4 of it, and it's ok, but not close to the same Devlan Mud. I recently purchased Seraphim Sepia to give it a try. I've seen Reikland Flesh, and it just doesn't look good.
I've been using Secret Weapon's Flesh Wash instead on historical figures, and saving my last old GW Flesh Wash for Empire figures. The Secret Weapon Soft Black has a bit too shiny of an appearance for me, although it can work on some things, and I'm probably going to try others made by them as well.
