I just started powder coating today. I have a decent stash of boolits that had been lightly alox coated and sized with a Lee push through sizer after casting, but were not re-lubed afterwards. So they have a very light coating of alox. I stripped almost all of the alox with a long soak in mineral spirits, and then gave them a quick wiping with paper towels to remove what was left of it. This seems to have mostly cleaned them off. This appears to have worked. Although the coating required two coats, and wasn't quite as smooth as I hoped, it is hard and doesn't flake even when hammered flat.
Does anyone here coat over alox? Do I need to remove it completely before powder coating, or am I wasting my time?
Any other suggestions for cleaning off the rest of my lightly alox lubed bullets before powder coating?
