Today I'm reporting on my new experience with Matisse's Black Gesso. I really like it. It's very thick, which can be watered down. However, if working on an abstract painting, applying extra gesso with a palette knife will give you extra texture without having to add paint! So it's more cost effective to do so. You won't have to use more expensive high body mediums to give you the textures you desire. I'll post a photo with final painting using the black gesso once completed.
Here's a great video on Matisse's gessos:
