There are many skinners pondering the new SPEC in the DCS World series....Including myself.
Through my trial and errors, I'll post what I find, and try to keep this simple. I encourage those with knowledge to share the wealth. :book:
When you look at the OEM SPEC *.dds files of the P-51D 'Bare Metal' skin, you notice the files use greenish and magneta colors to distinguish from flat & matte, to reflections.
From a beginners stand-point, "The greener it is, the more matte it is; The more magneta it is, the shinier & more reflective it is." But there's more to it!

For the most part, to achieve the colors that you see in the files, you have to adjust R(ED), G(REEN), B(LUE) values of each layer you create or want to have specular.
"To be honest, I couldn't replicate the colors manually."
But you can also use gray scale colors where black is matte, and white is shiny. If you had noticed, the official P-51D template has a SPEC group that nearly mimics the DIF group.
Delete the SPEC group that's in the template and duplicate the DIF group.
Within the duplicated group, add an Adjustable Layer at the top of the group.
Now slide the Saturation Bar all the way to the left.

In attachment 2, you see that the skin has a lot of light grey colors. If you're making a metal skin, it's ok. But we need a dull coat on this Desert Rat.
* Begin by creating a new layer and giving it a very dark gray color.
Now hide all the layers except the Color group.

For peace of mind; doing this unclutters the workspace and allows you to know what you have worked on already.
The next part is pretty much up to you adjusting the layers. Keep in mind the layers properties you used in the DIF group copied over. Adjust as nessecary to achieve your look.
