CA glue questions

[David Skolnik]

Don -
Very thorough explanation.  Thanks.  It sounds like ventilation 
problem is unavoidable. What would you do, or recommend?   Also, if 
the cracks in the bridge are indeed as small as Rex implies, would 
the water-thin glue act as gap fill with multiple applications? That 
is, would it achieve the same hardness, once cured?
