I bought this one for my 6" grinder:


It's awesome for deburring, knocking off rust, polishing drill rod, etc., but probably too coarse for polishing aluminum as it will leave a pattern on a smooth aluminum surface.

I've used a leather wheel with this on aluminum and it produces an amazing mirror finish. I was told that this is what Mercedez uses constructing their vehicles:

Those wheels are awesome, I use mine on aluminum but it is a bit aggressive so you got to be careful. They come in a variety of styles, sizes and grits so you should be able to find the right one for the task.

+100 on the AWESOME Scotch-Brite wheels. They are fantastic for deburring, polishing, and removing rust. I have a couple mounted on 6" bench grinder also. With careful use, makes sanded aluminum and brass look like a mirror. And yes, new ones are pricey. I picked up a lot of at least 20 off eBay for less than a new 6" disk (albeit only 4 or 5 were a 6" diameter, rest around 4"). There are variations out there; I see some offered that are basically a Scotch-Brite pad in wheel form. Mine are really dense, you'd give yourself a stroke trying to blow through the wheels.

Not only are they good for polishing and deburring, they do a great job sharpening knives, etc. I set mine one of my bench grinders to take an 8" Scotchbrite wheels, both medium and lite. They last much longer.
