I shot a jet with it about a year ago and I'm still alive. I think John has it right - just use normal precautions such as a good respirator. Certainly safer than Isocyanates.

I could not get the Klass Kote to flow out well using the recommended ratio of Klass Kote thinner. After additional thinning, it flowed out fine. You might want to shoot some test surfaces and see how it works for you. May not be quite as tough or durable as the Isocyanates, but my paint still looks fairly decent a year later.
