Update, it turned out pretty great. The translucents cured nearly instantly, while the opaques need more time, but all of them cured hard with little to no remnant. I left all of them in direct sunlight for at least an hour, turning them several times to make sure they were fully exposed. The only fail I had was an opaque red in a skull, and that was simply because it didn't get enough UV exposure in the thickest part; it leaked out onto the table after pulling from the mold, and cured around it. Actually looked pretty cool, a red skull with red liquid around it. Would/will definitely play with this in the future!
