I would disassemble the lamp then use paint remover.  Then use a good 
aluminum cleaner.  The original finish on the aluminum should restore as 
was. This: http://goo.gl/nzm2t or similar product.

Strip the paint off with paint stripper,then clean the mess off with fine  
abrasive fleece, and polish it with a mop on a drill. you can get fleece &  
mops to mount on a pigtail fairly cheaply, e.g.

For sandblasting, use walnut shells media.
http://www.kramerindustriesonline.com/blasting-media.htm

This is what the guys on the History channel show "restoration" use.
If it is really thin material, then use a stripper made for aluminum.

For that project, take it to a pro shop and let them do it.
By the time you purchased a sandblaster, the materials, and learn how to
use it properly, they'd have it all done and probably cost less.

Not suggesting you do this as I dont know how dear this lamp is to you, 
however when I got back into biking about 10 years ago I couldnt afford all 
the cleaning gear to polish aluminium,  so.... I made a thick disc out of 
cardboard, got some of that aluminium cleaner paste (cant remember the name) 
and used my electric drill at slowish speeds, it worked til I could afford 
the mops and stuff.

Somewhere in the industrial part of town is a guy with a blast cabinet 
who will do this for $10, plus two cold beers. It will take about 5 
minutes. The most difficult part of the job for you will be to find that 
guy.

Really?

Your cars have no aluminum bits that may be in need of having paint 
removed? If it's not strictly car related, GTFO?

well, polishing aluminum is something that many auto enthusiasts are 
familiar with...

sand blasting will not result in a polished finish.  neither will 
abrasives, although using a scotchbrite pad will result in an attractive 
brushed finish.

For polishing, nothing beats power tools, but if there's any corrosion 
that will need to be sanded smooth first.  I've had good luck with Wenol 
polish.  Once upon a time I sanded smooth and polished two old Ansen 
Sprint mags with Wenol... by hand... (because I had two polished and two 
machined) they looked (still do) great but I'll never do that again.

Take it to a place that does vaporblasting, you will be prating about for 
ages trying to get all the paint off.
and the link below is very much on topic for a car/motorcycle group.

Have to do this every day - (Aircraft engineer)

1. Remove paint. (paint stripper)
2. Remove worst of corrosion mechanically. (wet n dry and gentle fine wire 
brush.  NOT a brass one)
3. Kill corrosion - use Phosphoric acid (Jenolite). Wet for 5 min then wash 
off with water. Dry thoroughly.
4. If you are going to paint it you can prep surface with something like 
Alodine - it's a bit like anodising. (Not sure of how to get that other than 
commercially)
5. Polish or repaint. If painting use "Self Etching Primer" for first coat.
6. For polishing Google "polishing aluminium".

Good Luck

Ding! We have a winner! For a one-time requirement, it isn't worth it to 
buy the tools and supplies to do it yourself. Most every town has a 
metal-finishing job shop with all the needed hot tanks, nasty chemicals, 
media blasters, etc. And most importantly, the expertise to do it right 
the first time, without trashing the item. And they can even spray it in 
a nice clear sealer for you so it stays pretty for several years.

find a shop that blasts with walnut or pecan shells.  I think you'll be

The important bit is not the scratch the surface as its too hard to 
remove the scratches by buffing.

Any decent sized car body shop would have a cabinet for blasting. And vapour 
blasting is best for ali as it doesn't damage the metal at all. Either that 
ot baking soda.

The alternative way is to use a (I think it's called) a honing tool 
across the scratch.

It works by pushing the aluminium back across the scratch. Basically, it 
is a polished steel wire formed into a closed loop ring, mounted into a 
file handle.

I suspect you mean burnishing rather than honing but someone will
probably tell me I'm a cunt and disagree.

Seeing as you're correct, I doubt it. I'd still vapour blast (or simply use 
Nirtomors) to get the paint off and then go at it with either a set of mops 
and compounds if I wanted a shite and briny finish, or go at it with a grey 
ScotchBrite pad (not with a power tool) for the "brushed ali" look.

Grey, not red as that scratches too much. See "Angle Ginder" thread :-)
