I’ve used the Lureworks floating beads and believe this is what he is referring to. It changes the color in a major way and cannot be used for transparent colors. It also makes the plastic much softer and tear easier but it definitely has its place. I now use it more for tail and claw molds and less for the entire bait unless I’m making lizards and floating worms. My best advice is to stick with dark colors and sand cast molds. Also if you want to make the entire bait float try shooting it in a laminate so only the dark part of the bait has the floating beads in it.
