Question about glue

[blue66]

I have put on my luan and glued it down to the spars, using gorilla glue. My question is after I remove the screws and fill the holes will the gorrilla glue be strong enought to hold the luan without the screws. I am particualary worried about the areas that I had to bend the luan. Any thoughts?

Tough question to answer without knowing all the details. Gorilla Glue (the polyurethane version) is extremely poor when there is not a good fit between the adherands. In the below test, it was the only one that rated a FAIL.

If you want to bond wood to wood never use gorilla glue use tightbond 3 preferably and at the least tightbond 2 which is wood glue and the wood will fail before the glue breaks apart.

Actually while Titebond III provides a stronger wood to wood bond than Gorilla Glue, either has more than sufficient strength provided you have tight tolerances on the mating surfaces. If there is any gap or misalignment, a construction type polyurethane glue such as PL Premium is a better choice. (It has gap filling properties.)

+1 On the PL. IT works great.

+2 on the PL premium!

It is what is holding this together.
