This is all I have been using on mine. Cut it 30-40% with paint thinner. I did my scoops and wing with it and they came out awesome. And at $8 a quart the price is right.
That's what I have used not quite that much thinner I think it was 5-15% and the best stuff I have used is Endura Paint which they use here on helicopter and heavy equipment. Its not the paint to shoot with out proper respirator protection as it full of Isocyanates and other bad stuff.
