Howie - check out this site for info about Future, I know there is a counterpart in the UK by a different name: (it's in the first paragraph) Future is a clear acrylic floor polish by the way...

Elmers is white school glue, I am sure you have some there. (not the paste stuff, more like very thick syrup) if not Tamiya, Testors and a few others sell clear parts glue which does the same thing, but economically it is MUCH cheaper to use the school glue.
---edit--- if you coat your clear parts in Future before gluing them (and let them cure 24-48 hrs) any crazing from the super glue fumes will be reduced if not eliminated by the protection of the acrylic overcoat of the Krystal Clear.
