What kind of paint works best on MDF board?

I apologize if this is in the wrong section of forums, I'm new and I couldn't figure out which area to put it in. However, I'm in the process of building my own speakers, (going the morel route, etc...) to save money and I want a high gloss black finish on the MDF? Anyone who has experience, your feed back would be deeply appreciated!!!!
Thanks,
