Joey,
In the last nine months we have had one other customer come forward with a similar problem with bagged baits being oily and or smelling. He sent us the remainder of his unused plastic and we were then, and still now, unable to duplicate the issue in shop or find the source of this particular problem.
We can certainly ask some questions with the manufacturing chemist to find out if there is any certain thing or things that may cause this issue. We're hoping that some of the more experienced bait manufacturers here may have some insight as well. Any info is helpful and if you ever have issues with Do-It product I would encourage you to call Customer Service 319-984-6055 or reach out to me directly via PM or email.
Thank you,
Jerry
