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 can't help you with this, but I'd strongly recommend checking the inside
of the tank for rust as well. I don't have any idea what you'd do if there
is any, maybe fill the tank with Naval Jelly, drop in some BBs, and shake
it?

Good Luck!
