Is there something i can spray my mold with to make my sinkers smooth? all of mine iv done has little pits and lines on them. There solid all but the outsides. I noticed they seem to do better after doing a bunch and the mold gets hot but is there something i can do to help get smoother looking sinkers? What is smoking the mold? how do you do that? any info on this be great. I'm making 1, 1 1/2, 2, and 3 oz no roll sinkers with the Do-It mold and lee production pot bottom pour.
