By the way, do you know that the Gorilla Wood Glue you pictured in the photo is not "gap filling"? Gorilla Wood Glue is an ordinary PVA wood glue, like Titebond II. Wood glue is designed for tight fitting wood to wood joints between well-sanded, smooth, clean pieces of wood. PVA glues are arguably the best for woodworking joinery. Certainly they are the most economical and popular.
Someone else mentioned "Gorilla glue", meaning Gorilla brand's original polyurethane glue, which foams and is somewhat gap filling. It is moisture activated.
The best gap filling adhesive is two-part epoxy.
