Although I have not personally used this GM color yet, I've used another and its coverage, durability, and ease of use are super! If you haven't tried it yet, I highly recommend doing so. It adds depth and shine to all your projects!
I love Glimmer Mist but hadn't tried the Chalkboard sprays. They are just as great as the other sprays from Tattered Angels.
I love Glimmer Mist but I highly dislike this specific color! I didn't find it true to color at all! It came out as more of a gray color with gold glimmer.
