What kind of glue to use?
There are almost as many answers as there are modelers, as you’ll note from the comments below. A popular choice is PVA resin glue, also called white glue. This is sold under various trade names: Elmer’s Glue-All in the USA; Evostik Resin W in the UK; Aquadhere in Australia. Technically, most white glues are a suspension of polyvinyl acetate (PVA) resin in water. There are some variations. I think most so-called tacky glues are also a PVA glue, but thicker. from Stephen Brown
