I posted this in the Restoration section but didn't get any feedback so I'm posting it here in the hope that the experts will respond. I've been experimenting with getting out rust, stains and even pitting lately. I find that applying some Maas to a Micro-Mesh 3600 grit sheet works very well. I then apply some Maas to a Micro-Mesh 12000 grit sheet and the metals polishes up like a mirror! I know that this must have been tried by our experts and so I would like to hear your comments.
