I got the warpaint mega paint set. I'm really happy with it.
A few tips.
The paints are quite watery, saying that i still add a little water to them on my palette..
make sure you shake the pot very well to mix the pigment together, 2 mins should b good.
if you don't you may get a lot of the serum instead of the pigment, giving you a crappy base coat,which is what may be happening to you.
Several coats are needed to achieve good coverage. I personally prefer them to citadel.
Take model to club and we can better discuss it there.#
