I have a rectangular fuel tank that has some rust and flaking paint.

I want to remove both and re-prime and repaint, so that the tank looks
less menacing.

Attempts to do it with a wire brush on a 4.5" angle grinder were kind
of successful, but too slow and painful.

I would like to find a better way. I heard that some flap type disks
are better than wire brushes and are particularly good at this task.

I would not mind paying extra $$ for one if I can save two hours of
grueling labor.

Any ideas?

I don't know if they still exist, but I have a gadget that goes in an
electric drill that consists of a hub attached to 6 or 8 bunches of
pivoting wires. They are about 0.05" in diameter, and stiff. It's sort
of like a poor man's needle scaler. Once the sharp corners wear off,
they don't work as well, but you can square them up on a grinder in no
time. I've used mine on a variety of surfaces, including concrete, which
is how I know about re-sharpening the thing. It makes a hell of a
racket.

I tried a quick search on the web, and couldn't get a good match.
