I hate it when that happens. Use a hardwood block with a shallow slit to carefully roll the edge. Compare your work to a properly rolled edge as you go.
You can use the Avery tool and get it pretty close, I did exactly the same thing on one of my skins, it turned out fine (you can't even tell) but I couldn't get the Cleveland Tool to work because of the dimples.
Happened on one of my skins too! I used the Cleaveland tool. Start with it loose and tighten it down over several passes. Redimple the holes when you are finished. Came out just fine (to my surprise!).
