Works really well under water but you have to put a clear over it to make it a little more durable like a fingernail polish.
I love this stuff
Very high quality stuff will definitely buy from this company again
Glow-On is specialized glow in the dark paint:
Is not a gel and it dries to the consistency of synthetic cement.
Gels detach by virtue of their flexibility. Also Gels don't stand temperatures well.
Glow-On is a dense product. Imagine you buy an ounce of the best glow paint and concentrate it in a 2.3 ml vial.
