I've used Unibond for vacuum laminating skins and veneers to glue lams - but never for for structural work.
From memory the glue can be a bit tough to work at lower temps - heat blankets or a warm shop will be helpful in getting a good cure. I'm pretty sure there is a recommended temperature on the tech specs.
Is the glue lam structural? If it is - has an engineer signed off on the manufacturing process and the structural capacities of the glue and the interface to the chosen species?
