What can be used to polish a sub motor? My Audiomobile Evo has some discoloration. Doesnt look like rust. Its black stuff and I cant get it off with a scotch brite pad and 409. What can I use?

idk, You just don't want something that will scratch the motor up

rubbing/polishing compound and some elbow grease should take care of that.

Some scotch brite, rubbing compound, followed with some polishing compound should make it good as new.

I turned one of my DD motors from this:

Both of them are 3M polishing compounds usually used for automotive paint and such.

One is a heavier grit to get rid of swirls/scratches, the other one is a lighter compound to clean up what the heavier stuff left behind. Then usually after that you would use a wax/sealer to bring back the shine if this was a painted surface.

Oh, and I used a electric buffer. You can do it by hand but be ready for your arms to be sore. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Ill give that a go. How would a Nylon brush for a electric drill work out? Think that would work?

I grabbed some Brasso from the home cleaning section. Its an all in one metal/diamond polish. Almost all of it came up. I ran out of sandpaper.

Heres what I got. The backplate is supposed to be stainless steel Im assuming. Before and after shots with Brasso.

Not bad for a $2 polish.
