You can get it at Wally World, or any craft store that carry's the Aleenes Paper Glaze, I use it for the wet look on the babies lips, and a light Glossy look on the nails.
I know you can use that paper glaze to make spit bubbles, Myself I haven't tried it as I am waiting for that right face!
It's a suggestion I dont' know if it would work but it could. And you don't need to bake it it air drys...
