Define 'not hold very well', plz. I use the Medium grade of modeling glue I find at Hobby Lobby. From everything I can tell it's your basic SuperGlue in a bigger bottle and not so runny as brand-name SuperGlue.
But, I find that if the gluing surfaces of my two pieces (or just one of them) are glossy or shiny, that no glue at all will hold them permanently. I usually scuff the gluing surfaces with my file to guarantee a good hold. Usually, that connection holds while any hypothetical break occurs somewhere else in a non-glued section.
