I just built that same kit not too long ago, and I used Model Master enamels. and hungfarlow is right on, RLM 78,79, and 80.
I'm curious, are you planning on soft edges? That's what I did, but I do not posess the skill (at the moment) to do it freehand. So, I copied the sheet in the kit, and made masks by cutting out the mottling, and then used small strips of tape to keep the paper off of the surface. It worked pretty good, but it is slow going. half a wing at a time, and so on.
Good luck with the model - and please keep us up to date on how it's going.
