Is acrylic paint better than enamel?
Since professional acrylics are the priciest, they’re the most excellent choice. Because of the greater pigment amount in the paint, they have brilliant, long-lasting hues. However, you should use enamel paint on your model. The hues and durability of enamel model paints are superior to that of acrylic.
Can you put acrylic enamel over oil based enamel?

How does enamel cure?
Older Enamels cured through a process of oxidization. Basically, there would be no hardener/activator added. You reduce the product, spray it, then as air reacts with the binder in the paint they combine and change the chemical composition to become hard and durable. Even thought they have no activator they are considered a convertible coating (a product that changes chemically as it dries, and cannot be changed back). Acrylic Enamals are very similar but usually have a catalyst that helps to speed up the process as older enamels took a long time to fully cure. Acrylic Enamel catalyst is different from the hardener/activator used with urethanes. Some acrylic enamels, such as the Omni AE allow the option to use the catalyst or not use it.
What are the two parts of a urethane binder?

Is urethane better than enamel?
So what does this mean for you? Urethane is probably a better choice for the long term. An advantage to the urethane, as well, is that as you spray it, the (clear) resin tends to come up to the surface quickly basically leaving a super thin clear coating over top of your pigment (similar to having a thin layer of clear coat). Most quality paints have some UV protection added to the resin, thus, the thin layer on top prevents UV degradation of the pigments and the paint much better than enamels, which is even more important when spraying metallic colours.

Is urethane better than acrylic paint?
Urethane is a superior paint ; it dries quicker, harder, seems to be more forgiving in the application, and will last longer, but a fresh air respirator is a must if you'll be using it because of the isocyanates, as mentioned. Don't take this caution lightly; you've only got one pair of lungs.#N#As for acrylic enamel, you can get good results and you can get by with a good-quality mask in lieu of the clean air respirator.
