"You folks just don't get it. if you want to keep salt suspended ,you need a heated pot w/ a stirror"
you said the words your self.
I wouldn't assume I am running an off the shelf injection setup either (wouldn't hold up to continuous daily production )
there are ways to use a lot of salt in your plastic and NOT use a pot, to sit here and tell anyone that they NEED to invest in a pot and stirring unit in order to make baits with a lot of salt in them is insane.
To the Original poster, please keep at it. Add your salt after your plastic has been heated, add it slow while stirring. you will have to periodically stir, usually before filling the injector, keep at it and you should get the hang of it.
