Up to this point, I have been using spray graphite to lube my sprue plate. It works OK, but I have still ended up doing some damage to one of my molds due to streaking lead. I'm thinking of switching to synthetic 2-stroke lube, but I'm concerned that this would mess up my powder coating. Anybody have any experience with this? Do you have to degrease your boolits first? I know that you're supposed to use just the teeny-tiniest bit of lube, but I still worry that it might mess things up.
Thanks!
