Just for information.
Most solvents and industrial chemicals will cause problems at some time. The fumes from monocote have to be bad, ca is bad, acetone in ambroid is bad, resorcinol glue is poisinous (although I can't remember why), gasoline and jet fuel most likely still contain benzine, mek will mess up your liver, aircraft dope has lord only knows what that smells so good, polyurethane paint will definetely not do you any good although I am not sure about the glue but the fumes can't be good. There are many more in the same categories. I can tell you this from experience, having worked with all of these for 55 years in the aviation industry (ca only since 1965) I am having not only allergies but a medical problem which they think is caused by chemical exposure. Unfortunately the info was not readily available for years and then a lot of people didn't realize that it was serious when it was finally handed out (like me). So please use a mask or something to protect yourself as this stuff causes not only breathing problems that you have seen but genetic damage and cancer is also a possibilty like balsa dust (or I suspect any other sanding dust.
