Might be my imagination, but I think sizing afterwards is easier.

It also seems to help prevent the brass from re-tarnishing longer than regular polishing media.

Only thing to watch is not to add to much to the media - it will only absorb so much. Luckily, if that happens, just mix in more untreated media.
