You might want to be more patient. Mead can take a long time to clear; for that matter, mead can take a long time with just about any part of the process. I wouldn't expect it to actually be clear before the second or third racking, and at least three months after fermentation is done. But then again, it also depends a lot on what honey you started with, what kinds of additives you used, what yeast, etc, etc.
I've not used gelatin in mead, but it should work well. Follow Loopie's process. But I would wait till after the second racking at least before adding any fining.
