The System 3 paint is actually a water based polyurethane, not a latex. It is boat paint, and is water proof, and mildly fuel proof. If you add their cross-linker to it, it then becomes very fuel proof. It cleans up with water, and you can use water to thin it also. There's a good thread about using it on the RCG site if you're interested. I've used it on several planes now, with good results.
