Tamiya uses a convention in its color callouts I'm not familiar with.
The instruction sheet will say something like:
XF-7:2 + XF-4:1
Or
X-10:1 + XF-17:1
Is this just a simple ratio they're calling for? I.e., 2 parts to one part, or one part to one part?
I emailed Tamiya over a week ago and haven't heard back. Thought I'd ask the real experts here.
