Cool, thanks for the info.  I'm not quite done yet with mine but it's been 23 hours and the stuff looks pretty damn good.  A couple really bad pieces need to stay in but I'm quite happy with the ball trough and the metal "plastics".  I'll get some pics up to show.

Ball trough in tumbler: smooth and glinty in light, but a mostly hammered style finish.
Ball trough after polishing by hand: Mirror finish so good my wife could do her makeup using it.

Just sayin'...

Yeah, but it's not going to stay that way.  It's going to get hammered.  Plus from what I've read the shiny finish is just going to oxidize itself away anyway.

EDIT:  maybe the best path is tumble the parts that really need abrasion, hand polish the parts after? 

ChadTower:

On the way home I picked up some Nevr-Dull as shardian suggested.  Gave it a shot on one of the trough pieces I just took out of the tumbler - I have some pics of all three stages but not sure they will show the real difference.  The polish did improve it after the tumbling was done.  It took a lot of buffing to get the oil off of it.  No mirror shine but it looks nicer.  It concerns me a bit that the can says "do not use on lacquered surfaces" as I don't know how that would react with a playfield automotive cleared. 

Still, it's good, and I might use it on some parts later.

I washed the parts in the sink - no soap, just water. Rubbed it with my hands and all the residue came off. Then I just buffed it lightly with a clean microfiber rag. Zero oilly residue and a perfect shine.

ChadTower:

I thought I had all the residue off too.  Then I picked it up an hour later and could see I was wrong so I buffed it again.  Washed my hands, picked it up again... oily.  Mostly, though, it's the warning about lacquered surfaces that concerns me.

And Jim, no I'm not going to nevr-dull flipper brackets.  Duh.  I'm testing out methods for when I get to the stainless ramps.  I used the trough piece as a test because I already had it off the game.
