I've been experimenting with ways to keep the paint off of the hook eye. I take a cheap pair of pliers and drill out a space big enough for the hook eye to fit (clamps tight around the hook eye so paint can't get through) I grap the hook eye with the pliers heat up the jig head (I use a small torch) and then dip the head (while still holding the jig hook eye with the pliers) into a fluid bed. Sometimes the paint sticks to the pliers, but most of the time it does not. I'm still working it out. I use this when I powerder paint my drop shot weights and it works like a champ.
