Cant seem to find an answer to the above question. Anyone know?
In a word, yes. As always, the key is in the prep. And with florescent fixtures, a high-quality finish will require spraying or hand-rubbing. (I don't expect the effort to hand-rub would make that an attractive choice.)
I recommend cleaning the fixture(s), then thoroughly roughing up the surface with fine steel wool; also it would be best to prime them with a primer compatible with your choice of finish paint.
At this point you would not be limited to metal paint; almost any high-quality washable paint would be fine.
