I agree with Paul, in that nail polish seems to be the best in terms of
setup time on small features. If you are building larger parts however,
"red sticky wax" used with appropriate force as not to break the model
will hold through the investment/burnout process and can be adjusted to
fit.
In both cases, there seems to be little effect on the casting result.
Epoxy and/or "super glues" exhibit distorting behavior in the metal
casting and emit toxic vapor during burn out. This is not a serious
factor if you are using a well ventilated gas furnace. If however you
are using electric it can get pretty bad
