I just finished a Yellow Aircraft P-47 with Behr brand latex exterior flat from Home Depot. My adivce is if you use Behr brand, spray a flat clear over it. It is not gas proof like other brands of latex. After three flights, the paint has turned gummy anywhere it has come in contact with gas even though I have cleaned it. I am in the process of repainting my P-47. I purchased flat clear from Nelson Hobby that is water based and compatible with latex.
