Well, this is one thing I hate about Rendo's forums, can't find info you need, so I uploaded the images to my DeviantArt's "Sta*sh", basically a hiding place from the public gallery.

 

First up http://sta.sh/#/d1p9vm6nr80y This is the original, as you can see the alternate specular is taken up, so I came up with this after some failed attempts...

http://sta.sh/#/diltnagnq2x  Here is what I mean by the "math" function, adding both functions as the math function is acting as an extra "plug-in".  As you can see in both renders (postworked next to the material room), there's no difference on her face speculars.

The concept here was to "add" the glossy effect to the paint job without disrupting the face properties.

The whole face paint not shown, have had some ideas stolen & marketed, so I'm just taking steps to not have that happen again.
