Refurbishing Tail Light Bezels

So... I am in process of rebuilding the tail light assemblies for my '62 Dodge Lancer, and got the tail light bezel disassembled. Anyone know what to use to replace the silver inside the center bezel? I am going to make a mold of these parts, and pour new ones for my other side. The passenger side assembly was in an accident, and I need to rebuild it. 3181797487304738439.jpg -8248000337228511479.jpg
