Maybe if you are close to an edge it would be a concern, but it's just not a big problem, or at least it wasn't for me. What happens is the glue will want to expand up out of the joint, pushing the wood with it; so you have to cover with something like waxed paper/plastic wrap/packing tape... some sort of release agent... wrapped on another board and clamped (or heavily weighted) down to try and keep it all from pushing up and out.
Still, you will get some unevenness and will have to fair it. The GG sands a little harder than the base foam, so it is hard not to gouge and sand evenly. One technique that was suggested to me late in my build, but I found to work well, is to build a bridged shoe for your router that references the foam surface around a glue expansion, then float it around the area to skim everything back flush. Works pretty well on flat surfaces and more uniform than sanding.
