Chris,
I'm a fan of Enamels, can't seem to get the durability nor results I want from Acrylics.(which I use sparingly) The Radome Tan is an excellent interior representation IMHO. Recently I've used 40% Modelmaster S/G White with 60% Modelmaster "Panzer Interior Buff" #2104 on the interior of my Bristol Fighter, and really liked the effect. For exterior CDL I've settled on a 50/50 mix of Humbrol #74 Linen enamel with #2709 Modelmaster "Light Ivory", it's much lighter then the mixes I used previously.
If you have the time and resources try mixing up some small batches, try them on some scrap, and go from there.
Cheers,
Lance
