After seeing the defects in the mold the release was never going to happen but the wrinkles, certainly not heat or oil related. I suspect it has to do with the extremely rough condition of the interior of the mold not allowing free flow of the lead. I will see if my fancy overpriced Apple phone will get some closeups of it tomorrow.
