I have always used white glue. I have heard if you dip the canopy and windshield in future you can use CA, but I have been to afraid to try it. I have also used a new product called Hypo-tube cement. It is made for watch crystals. It works very well and will not fog clear plastic. You can get it through Micro-Mark.
