We have used powder paint on all our jigheads since we first started out. It's very durable, and apart from denting the actual jighead, we have found it doesn't chip. Just remember to bake at 350° F for 15 mins before using to harden it properly. As for the eye of the hook, we don't seem to have the same problem. On the odd occation that the eye does become covered, heat a darning needle with a lighter, and push through the eye with ease, problem solved.
