When I found out that Solarez has enough surface tension to make a dome over a hole, I drilled a 1/4" diameter hole, 1/8" deep, in my PVC frogs, painted the inside of the hole with glo paint, and then dripped Solarez into the hole until it had made a raised dome. Then I held it under my nail light box for five minutes, because it was thick, and I wound up with glow in the dark eyes with a convex top, almost like an eyeball. It really looks neat at night, and the fish like it, too.
