Hi,

You don't say what results you are getting now, so it's tough to say how to improve it.

Setting aside the "pick a buff" thing (I don't understand it either).....I don't think it's necessary to go past 400 or maybe 600 grit with the sanding. Your molds must be very smooth already if you can start with 400. And, going from 1200 to black/sisal is probably a step backwards, in my experience.

If an item is rough-cast, I start with 120 or 220, then 320, maybe 400; then sisal/black, spiral/black, then loose/green or loose/white depending on what works best for that particular alloy.

If you're going to do a lot of these you might want to get a buffing machine...your grinder is probably a little underpowered.
