Not sure if this is actually good. As soon as I opened the bottle, the liquid was globby and viscous, which was different from the other glow in the dark paints that I have used. It was sealed in a paper backing and then sealed with foil, so I doubt that air got into it. When spread onto a surface, it went on uneven and chunky, but can be distributed more evenly using a sponge brush. It dried within an hour. It did require a few coats for the glowing paint to work. It did stay put when exposed to water.
I had purchased this because it seemed like a decent value at two dollars for a good sized bottle. Considered the work needed to make it look decent, it was not worth it.
