Hey Tom,
Just finished mine. I have always used the 3m no. 77, and did here again. Unfortunately, most of it pulled up, even after letting each piece set under pressure for 2 days. I ended up using the DAP contact cement available at Lowes, and it is bonding MUCH better. I still need to redo several areas where the no 77 lifted.
I did not use it for this, but I have also been very happy with the Weldwood also.
Good luck!
John
