Have a fifty year old or so aluminium lamp housing that has been sprayed
black. The black paint is bubbling off in places and we wish to restore it
to a nice aluminium finish. Not neccesarily a shiny finish, a matt one would
be just fine; and probably easier.

Using wet and dry carborundum paper is going to be quite a big job to get it
looking good, especially around the detailed parts of it.

Is it possible to buy a small fairly inexpensive 'sand blaster' that would
do the job? Or even some kind of paint stripper, either of which would not
damage the aluminium surface?

Grateful for advice on how you might tackle this job.

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.
