Spoke to many about this subject after using many differnt paints, And i found the same answer USE AUTOMOTIVE PAINTS ! Can't remember the guys name from a Heli Funfly at Brooks Oregon, But people referred to him as a paint God and he told me the same thing. Yea there messy and the fumes can Kill you. But The outcome is far better than anything else available. Its completly fuel resistant and last for years. Go to a good local paint shop and buy Primer, Top coat, And clear coat. You can Buy some great paint on-line also. Get a Decent air gun, I bought mine at sears for $59.95 for auto paints and it works great. Or you can use a good quality Air Brush Gun it just takes longer. I have found the auto paints are also more forgiving, As in less runs and holds good in corners. Just be sure you prep, Prep, and more Prep and you will be very happy. His exact words where anything else is a waste of time. Besides its what Funkey and others use for there prepainted bodys. Good Luck !
