This is not much, but I repainted the tendons of my Sideshow LSB Warrior. Their original transparency and flashy color was hurting my eyes (plus the white glue visible below).
A little "juice" of anthracite gray (in order to keep them transparent), and some wood glue to add a little texture and glossy effect. I like it better this way
.
I also painted the teeth full chrome the day I recieved it, their original color was way too flat, I didn't take a comparison picture though.
