I only use enamels in certain circumstances when i really need to because of their drying time but I prefer acrylics because if you want a quick drying paint, that's the road to go down. Acrylics are also better because they have a wide range of other uses like being able to be sprayed by can or buy airbrush, which if you don't have they are a very good investment. For a F-111 I would use acrylics because you could spray it and have it dry quite quickly. Plus enamels take up a hell of a lot of thinners and yes the smell is nice (DON'T SNIFF IT!!!) but they can be very expensive. I hope this helps. P.S. you don't always need to thin the paint with acrylic but if you do use water because they are water soluble and they also wash h of clothes really quickly. they only need a bit of water to wash the paint of the brush as well.
