Sneezing and sinus congestion are the low end of the effects of regular CA if you are alleric to it. After many years without any problems, suddenly developed asthmatic bronchitis every time I got even a whiff. A few inquiries revealed even more serious effects are possible..heart arythmia for one. I switched to odorless with mixed results, some are good and some not so good. The best I have found so far is B&B Super Gold. It sets up a little slower than regular (like every odorless I have tried), but seems to work just as well. One drawback to the odorless stuff is limited shelf life. When not actively building, I throw mine in the freezer and have had no problems for well over a year. You have to let it warm up to room temp before using it to get good results, however. And I use aliphatic whenever possible just to stay on the safe side.

Good gluing!
