another glue?

I've seen a lot of discussion about the myriad of glue types, and what is the best, just adequate, and not good. Have seen the vids of Mike's glue tests for wood & foam. But I've seen nary a word about Glidden Gripper primer........... I recently saw a vid by a Lady who uses pink foam (Urethane?) for outdoor decorating projects (Holloween tombstones, etc), which she sells. After testing, she came to the conclusion that Gripper was the best & strongest glue/sealant for foam-to-foam (She apparently didn't work with wood, so none was shown).......So has anyone tried Gripper, and if so, could you share the results? Just curious, as I'm leaning towards a wood/foam combo weekender with canvas or linen skinning............thanks in advance..........doug
