A fluke i'd like to replicate

MegaP

Hi Dazzer's
I was playing around one day,came out with this texture,and for the life of me can't remember how I did it.
I'm pretty sure I didn't add a shader to the body and wondering if I played with specular etc.
I'd try both ways but as you know each joint has to have exact % if I'm to get the same outcome..tricky.
I'm hoping to achieve the white shiny glow.
Any help would be great
