The scar was already there.
I used so many colours. Black, grey, silver, copper, gold, orange.... Applied with spray cans, brushes, fingers and rags. Whatever I thought would work. I'm new to this also so it was just trial and error.
The Claw marks are a soldering Iron. The gouges in the jaw are a wire brush wheel on the end of a drill. I set fire to it (safety first !! Did it in the middle of my garden with a fire extinguisher at hand), pourd a little paint thiners on it, sanded, laquered, sanded, Dripped melted wax onto it and poured a black was onto the crown.
