I used it for the first time today. Pretty good stuff. Goes on thin. I had read some so-so remarks about it, but it's not bad at all in my opinion. I mixed it with vallejo thinner medium (60%) and distilled water (40%). Paint to thinner was roughly equal, 50/50. It can have a bit of blotchiness but dried smooth or in need of a small coat over any errors.
I had tried using mt. color leveling thinner first. Not a good idea! It seems to act very much like vallejo.
