The Mercedes had a broken taillight and so far I have not been able to find one at a junkyard. I'm going to try mixing food coloring with clear epoxy to patch the hole. The results turned out well. I used too much food coloring so it turned out more red than orange so if you plan to do this add just the tiniest amount of food coloring.
