Hand painting decoy, what kind of paint to use...?

[Full_Fan]

Sometimes the factory paint job just doesn't do it for me.  I'd like to re-do my B-Moble strutter and some others.  What type of paint would be best to use for hand painting by brush?  Something that's weather-proof and durable enough for field conditions and getting banged around in the truck?  I'm mostly interested in re-doing the heads but may touch up the bodies as well.

Any other hand painting decoy advice would be welcomed as well.

Thanks!!

Taxidermist paint for the head!
