Thats pretty much the lureworks type. I even mixed plastic in a small jar with the hardener and shook the snot out of it, mixed into my pouring plastic and stirred some more, then stirred some more began heating, stopped, heated more stirred, and I still got lumps. even heated slow.
I also poured a few dozen wacky worms the other day, and I though they were too soft. I bagged them today. What a difference once fully cured.
It doesnt help either that I have two bottles of something that its contents took the writing off off the bottles. Turns out their both softeners. One sinking. Baits were wayyy too soft.
