Aluminum will bend but if you try to bend it back it usually breaks.
The pros that repair these thing use heat.  Aluminum is not like steel
it is not that flexible.

To see what I mean take a piece of sheet steel, like from a soup can.
Now bend it sharply so that it creases.  Bend it back, then bend it forward,
then bend it back, repeat.  Eventually it will snap.  But you will be able
to
flex it quite a few times.

If you try the same thing with aluminum it will maybe go 2-3 bend cycles
then snap, a lot fewer than steel.  Of course if you heat it up with a
propane
torch (it is possible to melt aluminum with a propane torch) it will become
very flexible and you can flex it quite a lot.

If your wheel has a pooched in area and it is not losing air, you can do
more
damage with a sledge than just leaving it alone.  I would also guess that
anyplace that could repair it would charge more than an Ebay replacement.

Since you said you had factory alloys you should be able to match them
from a wrecker without a lot of trouble.
