i use revell contacta professional (has a syringe like applicator) for almost everything.
i tried with various super glues but don't like the fact that if you mess up, that's it, you're toast!!
[:0] i only tend to use it for v small bits or maybe tailplanes and the like; for big joints i'd rather use normal stuff and have to clamp it ie walk round the house for half an hour holding the plane in my "vice-like" grip!
crystal clear is ok, but it's tough to apply and has only limited sticking power; if you dip your canopies in future, you can avoid the frosting issue anyway.
that's me...
