Ok so I'm working on this large 16oz soft plastic lure and I need to make a hollow cavity inside the lure. I need to remove some volume from the top half of the lure. ( Might make it a rattel chamber to? Idk yet)
I'm thinking what will work best for me is to create hard plastic shell the size of the cavity I want. Since my lure is a through wire design I can just attach it to the wire.
I need a recommendation for what plastic I could use for this. It's got to be strong especially since it's going to be thin. The hard plastic has to also be able to withstand the heat of 350f hot plastisol.
Any ideas?
