Custom face paint

[ShadowMonk]

Hi all.

I plan to purchase a Devious Diesel face to replace my HO Bachmann model from shapeways, using the "Smooth fine detail plastic" material.

I am wondering which is the best paint to use for the face and the pupils of the eyes?

Also, when the face has been attached I plan to use a Matte spray finish, as I do prefer a matte finish to the models, which spray do you recommend?

Thanks in advance!
