am not claiming this to be great work, just a quickie I am doing up for my local GW store.
I am finding the foundation paints an absolute breeze to paint with and there is enough promise there for me to say with a bit more care and attention than I am currently giving them there is no reason the results can\'t be much better.
As to the flip top lids, I would never leave my paints open no matter what sort of lid it had.
And yes they do dry out much faster than normal GW paints (and I assume other brand paints as well).
Anyway here is an example.
The red is (from a black undercoat) Charadon granite, then homagaunt purple, then mechrite red. I originally then used macharius solar orange and iyanden darksun to highlight but it was a bit to dull so changed to using blood red, blazing orange and then a touch of yellow.
The metal parts are mithril with a wash of granite, then granite/scorched brown, then granite/scorched brown/black and finally black.
Oh and I could see myself painting an army now because god damn for me getting to that spot was really quick.
