Thanks for the replies.

Carrellh - that is the stuff. It says it bonds any type of wood, it is weather proof and is resin based I believe.

Outdoorhunting - Yes it is a liquid and unfortunately I could not find any Elmer's glues of any type.

I did try sticking two scrap pieces of lite ply together over night. I could not break them apart no matter how hard I tried. I think it will be okay. If I don't start building before the weekend, I will go to the local hobby shop and pick up some of their Aliphatic glue for peace of mind.

Cheers

Craig.
