Imron is awesome paint. I've used it for over 30 years and haven't had a problem yet. Personally I find it easier to spray than enamel but your results may vary. If you do decide on Imron, have 911 on speed dial or a defibrillator handy when they tell you the cost. You have been warned.
I'll second, that, I've also used imron on trucks and everything else that needs a durable good looking finish for over 30 years. In my case it takes a few hours before the isocyanides? kick in, nasty stuff, supplied air is the only way to use the stuff, still have a number of gallons on the shelf from decades back, seems to still be usable, the hardener ages quicker it appears.
