Daniel, I'm completely sold on these paints for the ultra matt finish. BUT, you have to shake the **** out of them and for base coat, apply multiple thinned down layers... for example, for the zouave's red pantaloons I did 4 thin coats of the base colour to achieve a smooth flat base to work over. That was over white primer BTW.
Just like women... beauty is in the eye of the beholder.
Cheers my friend
Colin
