Ecurie Martini is absolutely correct about adding a sheer fabric for greater strength for the weight than epoxy alone. I smiled at first, imagining a crash that would require such strength...but I suppose in serious competition the crashes can be pretty dramatic! You can also layup symetric pairs of fabric oriented +/- 45 deg for even better stress resistance.
On another note, in comparing 2 part resins to cyanoacrylates (superglues), the thing that comes to mind is the greater toughness of the resins, they will withstand a lot of loading and with a little compliance, which is nice. Meanwhile superglues are particularly good for little parts that you would rather have break off in a crash and reglue (not implying the superglues are weak, but they are more brittle). With resin, the glue may hold and damage the little part.
I noticed the suggestions about using a special glue for windows, but wasn't sure that any brands were mentioned (I probably missed them). Just in case though, Model Masters makes a nice one called Clear Parts Cement and Window Maker. It is fairly strong and dries completely clear. In a serious accident, as with the superglue, the windshield make come off, but is easily reglued.
