Blah, blah, blah…. And am I suppose to care and concerned? Pffftt…I've been building model kits for 45-50 years since I was 6; using rattle can paints since I was 8. All rattle can paints are flammable regardless of brand be it Rustoleum, Krylon, Testors (both enamel and lacquer), Tamiya, Duplicoat, etc… Not one single model kit has melted using Rustoleum spray paint.
I don't use Rustoleum High Performance Enamel Spray so your argument is irrelevant to me.
