I seem to have a bunch of stuff that *claims* to polish aluminum.
But, try as I may with any of it, I can't get close to the nice luster that the stock grill had when it came back from the repairs/polisher when the build was going on.
I have a hand-held buffer with pads, and I'd be good with taping off the grill and surrounding paintwork if I thought I could get a little more clean-up on it.
I know it's silly. But sometimes I like stuff shiny.
