This has cropped up a couple of times recently. I lost faith with super glue a long time ago as there is still a joint to fail.
I now use a solvent weld product.
It's called 'EMA Plastic Weld' and is made by EMA Model Supplies. I bought some from Squires Tools at a show but I would expect a good model shop to stock it. It cost me £2.85 for a 57 ml bottle. Use a cheap paint brush to apply as it leaves plastic residue on the bristles but keep b it and reuse. See http://www.squirestools.com/13-16.pdf , it's on page 297. It works by literally dissolving the plastic on both sides of the 'joint' which reforms when the solvent evaporates to give continous plastic. In other words there is no joint, just one bigger piece of plastic, so nothing to come apart.....
Simply make sure the joint fits together reasonably well, apply to both sides of the joint twice and leave for 30 secs, apply again then assemble keeping it all still. After a couple of minutes give the joint another 'paint'. Then leave in a warm place for 24 hours.
I've tried others (eg Humbrol Liquid Poly) but not all do all plastics or seem to give a good enough 'melt'.
I've used EMA for years and never yet had a failure. All those painted Mega-G bodies now with new EAHORC owners were done this way and it great to run into cracks. Backing a joint with very thin plastcard can also help.
Keep in the fridge to prevent evaporation and one bottle should last years!
Hope this helps
