The smell of urine is overwhelming.
That said, SD knows his chit as far as I can determine from more limited experience. I used steel wool just once...
As to the original question, to take a high gloss down some, I use rottenstone and mineral oil or linseed oil, as said.
I am of like opinion with Rost, but really, if they are close enough for "flash" to make a difference, they are close enough to shoot.... much ado about virtually nothing.
I just don't like flash....
