I agree that baits that extrude secondary plastisol in a short period of time are messy.I believe the salt content of the soft-bait will draw in worm oil. Salted baits also attract moisture and can create one helluva mess w/ various plastisols.Place you freshly poured baits on cardboard for a week or so to remove excess oils I tried mineral oil years ago and I thought it made the baits harder and a bit smaller. Possibly there are different types of mineral oil
