Since it is an older injury, there would be no way to really fuse the shell back together--that would have required immediate attention. But in this case, using epoxy would help seal the crack and basically create a sort of fake portion of the shell that will set and become apart of what's already there.

[It wasn't a perfect fix but it would definitely help--and could even be painted to match!]

Worst case is that it may take a few coats to help it match evenly so it's flush with her shell but I'm rather confident it would be easy enough to do!

See! Everything was going to be great!]
