so, I popped into my local GW for the first time in a long time yesterday, and the manager (who I used to talk to fairly frequently), points out that they're having a speed painting contest to promote their new Foundation paints, and he went into an advertising pitch about them.
I figured, it's free, I get a free mini and I can paint right before I go in to work, and also have the chance of winning a box of paints, sure, why not?
For the contest, we had access to the Foundation paints, black, white, a couple metallics and a few of their inks.
anyways ...
yes, they are quite thick, and they dry VERY quickly.
I tried using them straight (just to see), and it wasn't horrible, but it wasn't great.
I tried a 1:1 ratio, water

aint, and got a solid, surprisingly smooth basecoat over the black primer
I thinned it down even more and gradually mixed with white so I could do some layering, and it worked out quite well.
I tried drybrushing (good) but I did not try a wash.
now, even with how thick they are, I never had problems with clumping, and I was able to thin it out quite a bit and still use it (I even went approximately 10:1, water

aint, and it was still giving me pretty good pigment for layering)
I decided to try mixing it with one of their inks to achieve a desired colour, and it worked out quite well.
I don't think I'll shell out the $65 (cdn) to buy a box of the paints. (since I didn't win the free one)
But I DO think they'd be pretty decent for basecoating an army very quickly, or for speedpainting.
My main issue with them is that they dry out FAR to quickly, even when watered down. You would definitely need a drying retarder of some sort if you were going to use these regularly.
