Its a natural contact cement, it won't eat the foam. I am building a 120 sized Stinger, I bought all new thinner skins to sheet the wings. Others have taken the foam and wafered it and sandwiched the wafers with thin sheet balsa to lighten the wings. Glues, I used probond carpenters glue for most of the kit, I used gorilla glue to glue in the Robarts hinges, I used corebond to sheet the wings and 30 minute epoxy to join and glass the center section of the wing. I would worry more about all the sanding and itching from the sawdust. I lightened the fuse by cutting lightening holes aft of the wing saddle. I also set up for mounting servos in the tail. Stingers fly well, but unless you have enlarged the tail flying surfaces, to create a hooverbatics machine. I am going to start out flying it with a MDS 2.18 or a converted 25cc weedie. I have both engines. If, you want a 3d machine cut the wings down to 76 inches.
