How to attain a uniform dull finish.

I was playing around with a gray scotchbrite pad and my orbital sander attempting to achieve a slightly dull brushed finish. The finish had the right amount of light reflection for us but the problem seemed to be uniformity. Any suggestions on getting it to look consistent?

1) Polish it to a mirror shine, then wait about 10 years.
2) Replace all the panels with "mill finish" aluminum.
3) Walnut shell blasting...leaves a nice matte finish - but not "brushed".

I was raised in the spec home business . . . I always think of resale. If I disregard resale, I always think "reversible". If it's not resalable and reversible, I don't do it. My .02

Try Liberon Steel Wool 0000 with turttle wax or nuvite S with a good backing block, going to try it on my 1955 Safari. Liberon the highest quality steel yields long running fibers that allow for an even, consistent scratch pattern. The steel wool has been stripped of almost all oils for a low residue finish. Crumble resistant.

The grey scotchbrite pad I was using brings aluminum closer to a polish than the original mill. I think it could just go through a series of lesser abrasives to move towards a mirror (89 mirror anyway). Thoughts?

What do you mean by backing block? How about using it with the random orbital? The dewalt I have has loop fasteners that did a good job of holding on to the scotchbrite pad at least.

I've heard that using a Cyclo with wool fabric, like an old US Army issue wool blanket, does the trick. No first hand experience, however.

If you want a bunch of swirls, use the random orbital. No Airstream ever built has swirls in the metal, it should have a "grain" in one direction only. A buffer or cyclo polisher will give "swirls", but they will be so small as to be invisible.
I did use Scotchbrite pads on an Airstream to try to remove the worst of the marks where some joker sanded it. I used a back-and-forth motion to try to emulate the mill finish found on them. While it was a vast improvement over what was there, I can't recommend the end look as an ultimate goal.
