I had an offer from my Father-in-law and Brother-in-laws to help me set the top of the boat back in place this morning.

We mixed up the 3 gallons of the Poly-Fiber Super-Fil, and troweled it out from 3/4" on the sides to 1/4" in the middle to fill-in and bond the top deck to the epoxied wood.
Then carefully lowered the top down in place. It came together nice with a few extra hands.
We then laid down some plywood on the deck and 40+ 50lb sand bags to help keep the deck in place and level till it cures.
Now it has to cure for at least 12 hours.
