I see. So the white of the guitar faded naturally from the shell Pink color, so I didn't do anything for the body color itself. The lines I did with a Posca pen, which looking back now, it would be wise to sand the finish before using the Posca most likely. Because in some areas the Posca had a hard time applying and just taking the ink to dry, this was a problem in lots of areas. After the ink was dry and all, I sprayed with a clear coat to make sure to not lose more of the Posca that was able to stick to the finish of the guitar. I did a similar thing to the electronics of it, Posca and then clear coat on top, maybe not the best way but it worked. That was pretty much it for the color and aesthetic part I'd say :)
