We actually bought a flocking kit last year off of ebay, theres lots of them on there for fairly cheap. All it really is is a bottleto put the flocking in, a bag of white flocking, and a bag of white flocking.Theres a little more preperation behind it than this but its basiclly :You buy flat black paint, and flat white paint, and some sort of sealer stuff. (It says exactly what in the directions) You apply the sealer, wait for it to dry, then paint on the paint. Immediatly after painting the heads, you take your bottle which you filled up with flocking, and you just squeeze it lightly and the stuff which looks like very very black lint, goes all over the heads. Same goes for the white cheeks, you can even do the tails black too, it looks even better. As for durablilty, it holds up pretty well. You might have to touch it up a little bit in between seasons where some flocking came off, but overall, its pretty strong. It looks pretty good I think, looks much better than the flat black plastic, but not quite as good as the manufacturer flocked heads, but how could they? The ones in the stores use lasers and such. We dont really use are home - flocked ones that much anymore, mostly our new final approach, man they look good.
P.S. - everything you need for flocking costs a total of about 25$
