If you don't have painted heads or if the ones you have been using are scratched,

paint them or touch them up with fingernail polish. Hang them by the hook to dry.

My wife is not going to be happy you shared this tip RW!

Very good idea! However, if you cant bring yourself to use nail polish, i use Component System's epoxy jig head paints. They work great and are pretty cheap, but i would reccomend using multiple coats and in a well ventilated area (you may get a little light headed...). I find myself putting a few clear coats on EVERY jig head i use before it even makes it to the tackle box.
