Kimberly, I used the Design Memory Craft Glaze, and it is water resistant for just a splash, but you wouldn't want to submerge them if you're only coating the outside with one coat of glaze. One coat has always served my purposes just fine (but I make new jewelry pieces weekly, and rotate often!) but if you'd like to get a longer lifespan out of your beads, an extra coat of glaze *including* a coat on the inside of the bead with a slim paintbrush will make them even more durable. Thanks for asking!
