I have used both regular plastic model glue in tube (which tends to leave flaked edge as if not attached well) and the Testers liquid cement (which does great if parts are against each other til dry leaving a glossy coating and it also seals cracks like layer separation and makes water tight, plus is a strong adhesion I think better than super glue in some ways.) it drys at least as solid as the print as to filing/sanding etc.
I have not yet tried Testers other liquid cements like their clear windshield glue that comes in the wedge shapen plastic bottles with thin nozzle, it works excellent for clear plastics and I have even used it to creat tiny windows using the 'soap bubble method'
