I use the silver colored anti seize on the locator pins/bars on all of my aluminum molds as well as a little dollop on top of the sprue plate screw or bolt. This keeps things running for several hundred bullets and if applied sparingly does not migrate. The two stroke oil works too but is harder for me to control and needs to be applied more often. The two stroke oil is necessary for the bottom of the sprue plate. It doesn’t burn and prevents galling and lead adhesion to the bottom of the sprue plate or top of the mold. Use this on all molds not just aluminum. I’ve found the small bottle of Stihl 2 stroke oil has enough residue in it after using the rest for saw gas to last for quite a few sprue plates. Apply it to the under side of the plate when the mold is hot with a Qtip and then scrub with the clean end. Won’t get into cavities that way. If you don’t mix 2 stroke gas then the 1.5 oz bottles are easy to use and will last you a long time. I’ve used Stihl, Husqvarna, and Craftsman brand and they all seem to work for sprue plates.
