Thanks for your input Gail & Wayne. Since I have no experience in
fiberglass repair, I'll hold out for another chance. Is it anyone's
guess as to what caused the crack? The owner seemed as surprised as
I was disappointed to see it. I wondered if it was the fact that it
had been stored upright, outside (on it's trailer for the last few
years,) going thru our upstate NY freeze/thaws with the plug left
in. But that's only a guess. John
