If you don't know what you're doing with Aliphatic Isocyanates or have the equipment to spray it safely, don't use it, stick with enamel. It's not really a DIY product. There's a reason why it has safety warnings plastered all over the vehicle. Cancers of the respiratory system or lymph glands, or skin irritation, or children with two heads can really spoil a great paint finish. You would want to have a real good reason why Enamel won't work for you.
That said, if you have the correct PPE, it sprays in exactly the same way as enamel. No particular difference in technique, just that the pot goes off in about 3hrs.
