Like many others here, my CA "sniffles" have progressed into CA "asthma".  Fume protectioin with a good mask doesn't work anymore, unless used for the entire build process as dust from sanding previously (and well-cured) CA'd balsa seems to be just as bad.  Titebond II solves that problem, but I'm now in search for a case of Ambroid (remembering the Ambroid "swims" from the bad-old-days when you had a bunch of Ambroid joins going at the same time). <G>
