WOW. I spent 35 years spraying laquer and in the laquer thinner.
Somebody tell me that was good for me.
Sorry, you're dead.
I've never looked into any of the other solvents, but from painting 2 part paints I am sensitized to isocyanates, it's like a very serious asthma attack, your chest tightens and you can't breath. I stay completely away from isocyanates now. This was all from painting 35+ years ago, it's not a problem unless I'm around isocyanates, and has become less of a problem over the years.
