BCB will know better than me but I figure its equivalent to 1600 grit wet sand?Yep- just dont get the ones with any soap in them.Heck, Id get some 1200 grit and do it wet on one, then Id magic eraser wet sand it, then liquid buffer and see if I can make it go away myself if they are small and not to the flake.C.O.D.
