It isn't really a "mod" but as good a place as any to post. Today I was doing some cleaning and bulb replacement on my AC/DC Premium. I was putting a really slick coat of wax in the bell lane and noticed that the aluminum walls looked pretty dull. Thinking I could improve the ball speed if I reduce the drag I grab some mag wheel polish and taped off the play field and went to work. After a few minutes it looked pretty nice so I moved out to the other lanes and did those, it really made a difference as seen here:

I also did the metal at the base of the ramps but I still need to do the ramp walls. In the "after" picture you can see the bell lane walls

I'm really please with the results

Dooh you are right, I said that because they looked so dull it was almost like aluminum oxidization.

Thanks
It was a combo but mostly by hand, it really doesn't take that much effort (I used to poilsh up stuff on my Harley all the time). I worried about slinging the polish all over or damaging stuff so I used a Dremmel with a buffing wheel only where it was hard to get my hands. I used the tape to keep the metal polish off the clear coat no matter what method I used.
I do plan to finish more and when I do I will strip down the playfield a bit more so if and when I grab the Dremmel I don't worry about catching an edge and bouncing off into the plastics.

I have used this HD metal polish and it also does a great job.
