My brief experience with Black 4.0 was not particularly impressive. This video pretty much hits it dead on: https://www.youtube.com/watch?v=oKOC3Z9tDiI

I didn't compare with the other paints (I only found that video after ordering the paint...) or with the difficulty of painting (I got the intern to do it!) but in terms of the final result, that's exactly the same result I got.

I also have some of their glow pigment and it's a lot more impressive. This particular color doesn't glow very brightly or for terribly long, but the hue... glow pigment isn't supposed to be this color!
