You forgot to say that hardner or activator or catalyst(name depends on manufacturer) has the isocynate in it. When you open this to mix with your clear is the most dangerous time as it is more concentrated then ever. Of course it gets you again when spraying, plus the other chemicals. A fresh air system is the best way to prevent health problems, but a full face will work if you don't do it for a living, or use it once or twice a year. The eyes are one of the best entrance points for isocynates as V.waffe 3 has said. Most paint supply shops won't tell you about isocynates. This is a good warning for the DIY.
