I have a Tiffany style light fixture that I want to repaint. It is not glass and is not painted on the inside. It's heavy plastic with medium blue flowers and an inch-thick border around the top. We are moving to a farmhouse and I'm taking this fixture with me from where we live now and it needs to be repainted a 'barn red' color. What's the best way to go about this and what kind of paint should i buy?

Thanks!
