By far the best glow/ UV paint is those you make yourself. Go on line and put in Strontium aluminate powder-you should come up with some hong kong or Chinese suppliers-they will give you free shipping-too expensive from the States and they are re-pricing and re-shipping it to you. Go to industrial plastics and get some epoxy with the separate hardener(clear)about 2 hour is best. Paint your spoon with a base white paint-then mix up some 2 hour epoxy in those little ketchup cups you get in fast food restaurants-put in the colour strontium aluminate you require-the more powder you put in the higher the glow factor-about 2 parts epoxy to 1 part powder is good. Paint the spoon using dollarama kids paint brushes-you won't believe the hard,super glow in the dark finish you can obtain with just a little practise-better than anything you have seen in a store and will glow up to 8-10 hours depending on colour chosen. PS will not work by putting in water based paints-really only works in epoxy.
