Right now, none. Aside from the last one the rest are near undetectable.
Repair would entail removing the lip, pulling off the 3M carefully (if it could be without excessive additional damage), some careful sanding and epoxy-ing of the areas, and then clear coating.
It's small enough in person that even I can deal with it. Given the cold weather I'll be keeping an eye on the damage to make sure it doesn't spread, but for now I'll let it be. I think the layer of 3M over the entire thing helped.
