Improving it was easy. First, being soft foam, I shaped into a more character accurate curve by heating with an ordinary hair dryer. Then it was just aging. I cut some chips and dents into the edges for a more well worn appearance and gave it a wash of watered down dark brown acrylic paint. Next I actually rubbed muddy dirt on it here and there. Once dry I sealed it with a very light coat of matte finish clear spray. Finally, a couple of random splatters of stage blood and done. Took a 1/2 hour to do. 45 minutes if you count drying time.
