This terrapin was brought to me after a tractor ran over it at work and broke it's shell. I took it to the vet where the wounds were cleaned and the vet wanted to mend the broken shell with a fiber glass bandage but they didnt have in stock so I went out and bought pratley steel putty to make a temporary fix. I had to sit with this smelly terrapin in my hand holding it so the putty can set for 45min but the result is stunning. 3 month later I removed the putty and the break is healed. Sorry but I dont have a pic of the break before it was set.
Before.
After
You can still see the break line but its healed nicely.
