I have seen posts over the years back and forth about cooking scents into plastics. The main argument being the scent “cooks off” as you raise the temperature of the plastic. Since the plastic is not boiling I’m not sure I buy into that idea. I have tried it with some Toad Explode a few times with ok results. I just use Pro Cure crappie and panfish super gel. Small bottle, easy to apply, stays on the bait, and doesn’t keep on giving like a stinky pack of baits.
