Subscribing to this thread. Just picked up a '72 blazer and to say my rear hatch is "in need of help" would be an understatement. It is cracked clean through at the bottom span and has cracks and a bad prior repair at the hinges...I have some experience working with fiberglass, but this will be a challenge, getting the new resin and fiberglass cloth or chopped mat inside of the hollow structure. I would be interested to see how others have gone about repairing these!
