Christine-
It doesn't look to me like the skirt is cracked, but I could be wrong. If it is not, a good color sanding will take that right out. I'm serious, you should have seen how trashed my rocker was on the drivers side (previous owner was a short female) and you cannot tell at all.
Might just be an excuse to get a professional detail for your baby.
