Quoted from fusion301:

Im telling you it doesnt get much easier then to use the flap wheels, I will try and do a demo video - also gets out deep ball trails that would require lots of elbow otherwise. Also takes out heavy scratches etc on lock down bars, makes them look nice and new with out much effort.
I finish it off with a scotchbrite pad by hand to fine tune

Quoted from PinballMikeD:

Extra work builds character
FYI - the dremel is more important for removing grooves then anything else. No need to have a track in a shiny new rail right? There are tons of different ways to do this, do what works best for you. Experimentation is always good
