Take it from someone who has painted quite a few cars. Unless you have an air-supplied respirator I would stay away form any "catalyzed" paints. The isocyanate's are very dangerous, just not worth the health risk. I could tell you stories but I won’t.
I would recommend Dupont Centari. You DO NOT need to add hardener (which contains isocyanate'). It is easy to work with and you can color sand it for a beautiful finish.
