I have had poor experience with Gorilla glue. I would look into West System Epoxy, a marine two part epoxy which is stronger than the wood you will repair.

Hello again, engineering friends.
What is the best suited EPOXY to use in Wood Repair (cracked DFL beam) in "combination" with bolts holding it together.
Thanks
