Have you thought about using latex exterior house paint? Roy Vaillancourt of Vailly Aviation has a whole write up on how to do a latex paint job. The good thing about latex is .. you have several chances to get it right. If while painting you mess up, just use a wet sponge and wipe off the paint and start over. With auto, it may look better but you only have one shot to get it right. There is no wiping off and starting over. You could wait until it dry and sand it off. Another good thing about latex, you could finish painting a plane in one day or just a few hours depends on your scheme. The clear , some say should go on when the latex is fully cured which takes about a week. But in terms of looks latex painted warbirds look fantastic. Do a search and you will see, and it is a hell of a lot easier to paint than auto paint also minus the smell.
