I own a bottle of this stuff, and it's not really as amazingly black as it looks on camera. Sure, it's pretty damn black. But it's easy to see the imperfections and stuff up close. There was a video that compared it to black felt, which is pretty similar.
And no, this is not Vantablack. It's just some special acrylic that can hold a lot of black pigment, and a lot of black pigment. Vantablack needs to be "grown" with high temperatures so its usually seen on aluminum foil and such.
Overall, this is pretty cool. I could definitely believe that it's the blackest acrylic paint in the world. However it doesn't create a "black hole" or anything.
