: Several cracks have appeared, which could be fixed, but there seems to be
: "ripples" in the outer glass at each cracked strip. There is a
: very slight "whitening" of the area where the glass seems to be
: a bit stretched. If I just fix the strips and finish out the inside, the
: inside will be fine.

There is really no way to get rid of ripples and whitening without sanding away the glass. You could just sand locally to the problem and then patch in glass over the sanded areas. This will tend to leave a halo around the perimeter of where you have sanded into the wood. If you can sand enough to get rid of the glass, but not into the wood, you may avoid the halo. Otherwise it might require sanding the whole thing it you want absolutely no sign of any problem. Personally I would just sand locally and learn to accept the slight sign of a repair. You will probably be the only one to notice.
