I am using glass beads. A friend works for a highway contractor and they use glass beads to make the center stripe on the highway reflective. They had a huge tote that got rained on and I got it for free. I laid it out on tarps in the sum and dried it. I got 2 55gal drums full of dry beads. They are slightly smaller than beads used for blasting, but they work great. I have a lifetime supply.
