I have some funky flock that I was just about to sell! I never got the gumption to use it. Send me a pm if you'd like it.
As far as using it goes, I can't find a tutorial at the moment. But I think you start out with a thin layer of glue on the pony, then sprinkle flock on. Make sure the pony is on top of paper so you can reuse the flock that didn't stick. Then you let that layer dry, then glue again, then another layer of flock.
