Daryl,
I use Harbor Freight PC powder. I apply it with their PC equipment. I started doing this to some (not all) of my cast bullets back in 2017. Use a Wal-Mart large counter oven to bake them in. I use a metal tray covered with aluminum foil to spray them on. Then I transfer them to another tray with tweezers that have a silicone sheet on tray to bake. Eaze Peze.
