I make a lot of my own jigheads also. I wasn`t happy with the hooks offered in most ready made ones. They are offering a lot of better quality hooks in them now but the price is high, I make what I have a mold for.
I don`t paint them, I use powder coating, soft plastics don`t affect it, I also put glitter in hobby epoxy and brush in on some over the powder coating.
I get my lead for free also, got my powder coating for free, hooks run about 9 bucks a hundred for most but I also use some that are more.
