The more that I think about it, most of my mold prep applies more specifically to bullet molds (sprue plate honing, stress relief of aluminum molds to ensure that alignment pins stay put, mold handle prep, etc.). Ultimately, the cleaning of the mold blocks is probably the only part that applies to fishing tackle. I would typically soak overnight in carb. cleaner. I guess my prep will be limited to that.
Thanks,
