Lew Adams passes this along:

Rather than removing, repairing, and/or replacing the leading edge skins (expensive) I tried a local Austin guy advertising "Dentless Body Repair."

He showed up with all kinds of specialty tools, suction cups, rollers, lights, etc., and within a few hours the dings and flat spots were gone! No drilling rivets, pulling sheet aluminum, re-painting, downtime, etc.

I figured... what do I have to loose? Cost a few hundred$ and it was done!

Evidently he has been doing this a long time. Would probably work well on any hangar rash too. His info is below. Perhaps this will help others.

Best,
Lewis
