I came across this a while back, I have not tried it yet, but I thought of it reading this post. It is for making an inkjet iron on transfer that glows in the dark. I too have tried the paint and I did not like the end result. I did make a wall hanging and I painted my grandsons palms with the paint and we did their handprints on it. It did not look as bad with thick paint this way.
