hello everyone. I have been trying to create some waterproof labels for some glass bottles which I am going to fill with lotion and toner. I got some clear glossy labels which look great on the bottles. I was told you could spray the labels with clear spray paint to help prevent water/oils from smudging. Which is better to use....enamel or acrylic? I have tried the acrylic and it seems to be okay, but for some reason when I peel the labels off the sheet and stick them to the bottle, I have an area around the diameter of the label that looks a little bit milky? Is this the spray making its way under the label? Any better suggestions?
