A friend of mine asked me to make a hard nose plastic worm. He told me he loved how soft the worm is but it did not stay on the hook. Has anyone made a harder nose bait? What did you like/dislike about it? and How do you go about doing it?

I am new to this. I just ordered my first fine salt and got it in. How much salt do I add to my plastic and do I add it before I heat it or after? Thank you for your time.
