Hi,

Well actually the problem is solved.  These ripples occurred from the wings
sitting on the trailer.  There were a couple even larger "dings" in the wing
top surface.  I brought the wings home from the painters last night and put
them on the aircraft and in the hour I was there the surfaces had relaxed
almost back to where they should be.  I am hoping that a few hours in the
sun will have them looking good as new.

Paul
