No need for the recipe, unless someone else would like to know. Just
wondered what medium you worked in. I work the same: Acrylic base, oils
and Humbrol. I use some other enamels too, MM and some auto modeling
paints for metalics, but I like Humbrol generally speaking.
I never know my recipes. I just mix until it looks right. I know
whether I need more red, or yellow, or what have you, and I just dial
it in.
