Fiber Glass Hoods and Repair.

I am considering buying a fiberglass hood for a 1967 through 1969 Dodge Dart. I found one near me on Craigslist that looks a little rough in the picture. He doesn't have any other pictures and seems unwilling to go take more. It could be just the picture bit it looks like a crack near the front I know some people can work fiberglass and repair that kind of stuff.
I have 2 Dodge Darts . Anyone have experience with fiberglass and what to watch out for?
