Hi, I'm not sure either- I'd google it and see if you can find any forums.

What is the finish that is on furniture now? Colored lacquers may be a good choice. You can also use latex paint and then topcoat with a waterborne urethane, which won't shift the color, but will add durability to the finish. But you have to check for compatibility with the existing finish. If fingernail polish remover (acetone) softens the finish, it should work with lacquer, but that will require spraying the finish. Try a test in a discrete area. Lightly scuff sand for mechanical adhesion and then paint. Gloss enamel is hard to hand paint and have it flow out well. Truthfully, any gloss finish requires a smooth surface to begin with, and then each coat must also be smooth. Whatever finish you choose, spray if possible. Hope that helps.
